I disagree with Elessar, Burnas are hella useful, probably not AS useful as Lootas but put 10 in a Battlewagon, and you can disintegrate marine squads in a single shooting phase. (decent armor vs 99 hits? eh) Coupled with a deffrolla you can even pop rhinos or tanks and then torch the guys inside.
I dunno how an all burna fighting force would work, but if you take a bunch of Power Klaws as well, you should be able to kill at least a few tanks. Eldar will still give you trouble though.
EDIT: My entire post has been said already...My bad.
I'm all for playing this game, but you don't have to be a dick about it.
