He's not. D-A-C just has his own ideas of how the game should be played and expresses them on the forums.
Considering all the disagreements we've had about how the game should be player with regards to competitive vs casual, I think that counts as the nicest thing you've ever said about me.
That's just it, it depends entirely on who you're asking. For some people taking more than one of anything is spamming, for others they don't care unless the unit is a powerful one. It's another one of those things that most people don't even necessarily agree on the definition most of the time and thus it's very difficult to quantify. Hence why I don't take it seriously.
I think spam is spam, when a person is using a particular unit as a kind of crutch for his army.
'Oh this is the best unit, in terms of how easy it is to use and its overall stats ... spam, spam, spam.'
This is most notable in codices were there are viable alternatives to the model being spammed.
In the Chaos Codex spamming Obliterators and Daemon Princes (in some peoples view) is necessary to win.
But when codices like Blood Angels, Space Wolves and Daemons come out, and have multiple choices of very decent units, and people spam, Razorbacks, Long Fangs and Heralds of Tzeentch then this becomes a problem IMO.
Now everyone says that I complain because I lose ... not so.
Once you find the weakness of the spam, in terms of better units against them, or their tactical flaws, they are actually pretty straightforward to beat.
But ... I have to change my army to play such opponents, I can't take chances with some marginal but fun units.
I have to drop things like the 30pt Boon of Mutation power, which is incredibly fun but very unreliable. So because more and more opponents are spamming in their armies, in order to stand a chance, I often have to alter how my army is set-up.
Also how these armies tactically play out is always the same, because they are based on spamming the same units, so the whole army has the same strengths and weaknesses, so these games in general always play the same every time, with few real changes.
No fun unexpected twists and turns because when you beat one unit, their is two more of the same. Whereas when my Seekers are wiped off the bored, they are gone, and I now rely on Blood Hounds, and IMO from a narrative side of things, this is actually really enjoyable. Whats more fun that killing a HQ in an epic showdown? But if there are two of them ala Daemon Princes or Heralds, wheres the fun in that?
So other peoples choices end up limiting MY choices. That's why I keep pointing out that its a social hobby, what other people do, effects me, thats why I raise issues such as competitive vs casual, unit spamming etc.
Now maybe the answer is, now when to have super awesome competitive battles and more fun and casual battles.
Most people though don't like one style or are unwilling to adjust when necessary and to some extent this even includes me.
But its still necessary and important to discuss all the major styles, attitudes and trends of how people are playing the game of 40k because it is a social hobby.
