The word bearers are a bunch of wimps who build churches.
Arguably the most dedicated of all the Legions to the Emperor before Monarchia, and, considering that they conquered more planets than any other legion in the space after that, I would hardly call them wimps.
The world eaters tactical book is charge directly at nearest enemy regardless of what happens
They preferred direct assaults yes, and their effectiveness at this was shown in great detail when they fought the Wolves. When it comes to wiping out your opponent to the last man the World Eaters are one of the best. And remind me again what executing a legion entails?
Emperors children is more concerned with perfection than getting shit done.
Ok that is just total BS. They strove for perfection yes, but they did it through application of their skills. They still prided themselves in having a legion that had specialists in a number of fields and could operate with peak efficiency under various circumstances
Ultramarines are incapable of thinking out of the box. Frankly by this time the one guy who considered the possibility of astartes vs astartes combat was disgraced.
Because the idea of it was so alien and down right heretical
at the time. I think if they had been put in a position by the Emperor where they had to consider fighting other astartes beforehand, they would have had no problems developing very effective ways to battle other legions. Like they did, y'know, after Calth.
The dark angels I really don't know the lion probably had his own agenda
It has been repeatedly shown now that the Lion has never been anything but loyal to the Emperor and Imperium. Just because he liked to play his cards close doesn't mean he had another agenda. Not to mention their access to exotic tech and weapons the other legions did not have (and therefore probably had no knowledge of their capabilities or how to best defend against these) would most certainly have been an advantage in any conflict.
Death guard did frontal assaults
Among other things. They were generally stuck in some of the worse and most hazardous combat environments, where they actually thrived. And, as shown in Vulkan Lives
, some of their chemical weaponry proved very very effective against fellow legions.
Iron warriors and imperial fists worked best against walls
Well, the Fists were also noted as being one of the most successful, and, as the Lion notes, most efficient and best functioning legions around. They wouldn't have been regarded as such if they didn't have a fairly broad skill set, siegecraft and defence merely being chief among them.
the luna wolves used tip of the spear tactics.
Their preferred tactic yes. But they didn't become the most successful legion of the Great Crusade by being totally one dimensional. You are seriously underrating them here.
blood angels were CC specialists with have a serious flaw.
Like the Wolves with their own genetic curse?
Alpha legion avoid direct combat with complicated plans
For the most part. And they were able to get far closer to actually managing to kill a primarch than the Wolves have so far.
Night lords use terror
Yet were capable of engaging in a long campaign against the Dark Angels legion, where the application of terror was not a viable tactic.
Raven guard use stealth.
Stealth and hit and run. Great for sowing confusion amongst enemy ranks. And if the terrain suits smaller engagements, excellent for eliminating enemy forces piecemeal.
salamanders like to burn things
They preferred fire weapons when they fought. They also had a lot of armour, vehicles etc. compared to many other legions. This does not give us any idea with regards to how effective their tactics are against another legion, or even what tactics they actually used.
Iron hands appear to use overwhelming force
Yet capable of adapting and coming up with new strategies, such as when the Eldar turned their own mechanised parts against them during that one campaign. So I see no reason why they couldn't adapt successfully to fighting another legion. Hell, the Isstvan suvivors have shown, especially the Iron Hands, just how resourceful they can be.
White scars use fast attack.
So they liked to use speed when they fought. What's your point? Doesn't detract from their effectiveness.
The 1K sons are psykers whatever their others tactics are I don't know.
The Thousand Sons often used guile, trickery and diplomacy to achieve compliances. But we saw in A Thousand Sons
that even outnumbered, taken by surprise, facing some forces specifically made to combat them, as well as the Emperor's personal force, they still managed to give the invading force a serious mauling. Hell, up until that one idiot captain overused his powers and set off the catastrophic chain of events that put them on the retreat, they were actually winning. And they, along with Magnus, still managed to escape. From under the Wolves' noses.
Then finally the wolves, they do the berserker charge of the world eaters and BA but they seem to have more control over it, they also use pack tactics as evident in the night of the wolves.
The Blood Angels never showed any control issues on a large scale before Signus. The breakouts of the Red Thirst were really limited to individual cases before then. So that doesn't really hold. And explain "pack tactics"? Other than the World Eaters who were lost to the nails, pretty much every other legion would have come to their primarch's aid if they thought he was in trouble.
Aside from the DA and maybe alpha legion the wolves were the only ones who could be executioners, everyone else either didn't specialize in what it would take to kill an astartes. Or wasn't flexible enough to get the job one.
Firstly, though it was their preferred tactics listed above, it was by no means the only thing they were capable of. The Emperor made the Space Marines to be the galaxy's greatest fighting force. Capable of fighting under any circumstances against any foe. All your "analysis" does is seriously downplay what all the other legions are capable of in order to make the Wolves seem more special than they were.
Every legion will know as much as any other how to kill a space marine. Seeing as they are all themselves space marines and well aware of what they are capable of. Also, if the Wolves were such specialists, why didn't they totally murder the World Eaters (a legion whos abilities you seem to enjoy underplaying) or why did they have such a hard time against the Thousand Sons, even with the Custodes and Silent Sisterhood backing them.
And quite frankly, calling the Wolves more tactically flexible than the Fists, Emperor's Children, Luna Wolves, Ultramarines etc. is a joke.
