Tier lists are a reward to the player who wants to be fluffy. Over taking optimized lists. And by reward, I mean typically lower point costs, allow more of the same unit to be taken, and the most common +1 to see who goes first.
If you want to learn, I'd be happy to help, but any of the regulars in Abington on Thursday are of good help (Ian, Rich, Matt, Ed, Robby, Drew, and myself) really anyone but Rick.
Robby and Ed are my star pupils, and Ian taught me, so there's a chain of success.
