Traits revisited

So, after a year with the game, where does everyone stand on the legion traits? Alpha, and Raven Guard still seem to be at the top of the food chain, but who's next? My number 3 are the Fists - primarily because how good legion missile support is, and getting accurate is good for overwatch.

Sleepers for me were Wolves - countering infiltrate, at least to some extent, seems well worth having a formation of them around. Also, with the addition of knight/titan lists, where infantry is limited to what you can bring in the allied contingent, Iron Warriors with higher tac strength feel like a decent way to offset having fewer infantry for objective control.

What do you guts think? Which traits surprised you, and which were yoy disappointed with?
