And some armies have no Lords of War. And some armies have no 2+ saves. And some armies don't have skyfire. And some armies don't have flyers. And some Lords of War are ridiculous and actively nerf your side (hello Lord of Skulls). I think you're missing the point here.
You can bubble wrap your superheavies to avoid first turn meltas. It's not that difficult to pull, so don't get too excited about being able to assault a titan in turn one: it's nearly never going to happen.
As for killing enemy armour on turn one... I have exorcists. If I don't get first turn, I automatically lose them on a 2+ and then it's gg bye.
I wish my army had fliers.
I haven't heard anyone complaining about double FoC, ever. Allies were whined about to no end, but as a matter of fact aside from one or two particular combos (Eldar/Tau or Tau/Eldar and pretty much nothing else) it does nearly nothing to make you more competitive, unless your army sucked in the first place, at which point it's begging the question of why you're not switching already.
Super heavies make you play a different game and add yet another level of codex creep. Say to my face that the Eldar Revenant and the Lord of Skulls are equally powerful and valid without laughing, if you can.
Which armies have no lords of war?
You're missing my point - just go with it and play to have fun - the game isn't balanced regardless of whether or not you play escalation.
Lots of D-weapons are blast so they scatter - they might miss you on turn one. Or you could put exorcists in different corners of your deployment zone so that unless you've got a silly amount of d-weapon off one LoW (Revenant I'm looking at you) they can't kill it all in one turn. And if you kill his troops, he can't win unless he tables you. D-weapons also have to roll to hurt now, so thats a slight nerf too.
At the end of this - it's still a dice game. Who hasn't ever had that one game where they couldn't roll a 2+ to save their life?
Sisters get LoW fliers according to the above list. They might not be good (I don't know) but you get them.
You've never seen all the complaints about double foc? All the hundreds of lists/tourneys that are 1999+1?
Allies aren't complained about? How many armies have Tau allies? I've seen posts from people complaining every army in the place they play has Tau allies. Especially with the formations you can bring now.
The revenant and the Lord of Skulls aren't equally powerful, same as a guardsman can't beat up a phoenix lord.
But then, show me a LoW choice available for eldar from GW for £95?
If you want something to take out a revenant, bring a super heavy flier. Blast weapons can't kill fliers.
So, for sisters you get these
I've no idea if they're good, but they look cool and will probably kill stuff. And isn't that the point of 40k?
I think I need to get the escalation rules so I can field my stompa. Poor old brian has never been used since I built him a couple of years ago. I will spruce him up and make him more battered, then see how he gets on. He only has the D strength close combat weapon so I expect him to last slightly longer than my truck
Brian looks awesome
He's not the end of 40k, he's a very naughty boy
