At the ATC each player on the team must use a different codex to the rest of the team. Therefore if the top 3 players on the Westgamer Generalship Table happen to be Grey Knight players and all 3 wish to go to the ATC, 2 of them would have to be excluded as the, couldn't use the list that got them selected. Following the logic above.
That's pretty much correct, although fortunately a lot of our players use more than one army (especially the MEQ players where a lot is interchangable), so two of the top 3 might have a second army they have managed convincing results with as a back-up.
If they hadn't already they'd probably find this sufficient motivation to enter a tournament with a different army just to get that result.
Sticking with me as an example, I've had 1st places for Imperial Guard and Blood Angels (once with standard BA which could count, once with some Lucius pods which wouldn't), so if someone took IG I'd fall back to BA, assuming someone hadn't already taken that in which case I'd want to enter something pretty soon with something new!
That's just the nature of the ATC, they simply don't allow more than one player to use an army from each state. The qualifying players will have to be a little flexible, but I am sure we can work it all out amicably.
It is possible that a good general could use Imperial Armour to derive some advantage through clever list building; however that is certainly no different to using any other codex.
True, and if they would let him come to the ATC with the clever Imperial Armour list then it wouldn't be a problem, but they won't. That's the difference from any other codex, and it applies to the vast majority of tournaments especially the top competitive ones.
Sure it might take 54 vendettas to kill 3 Achilles on an average day but that isnâ€™t always the case and not every day is average. Unless of course it is all about best list builder and generalship has no bearing on the game
I expect you're well aware I usually agree with you that tactics and plans are far more important in 40K than army lists, but yes it is actually my opinion that if someone brings three Landraider Achilles it is all about army lists, and generalship has little bearing on the game.
Some armies simply cannot deal with it, they don't have the tools regardless of player skill. Brendan is unlikely to disagree with this
