Int -> Int -> SoB -> SoB -> TH -> MCe -> Fin -> Fin -> WK -> WK -> HR
The description of AoMC, "You hate chance, games of chance, you hate chance so much that you crush dice whenever you see them" describes me pretty well. I usually play on AoMC, to the point where my high scores only has three entries on the first page that aren't AoMC.
Second-favorite is a tie between all pistol traits that aren't Bullet Dance. I disagree about MSS. MSc is a better pistol trait if you don't mind using other weapons for the first half of the game. You get Intuition sooner, you get a nearly guaranteed Storm Bolter Pistol (with a nearly guaranteed Sniper Weapon Pack to slap on it), and it doesn't block SoB if you're playing Ao100 and want to do even more damage. Against the same enemy with 2 armor, with the same ammopack, my MSc-pistol build can put out (at level 16) 337 DPS assuming I roll nothing but 1's - or 487 DPS average. Getting numbers like that on an MSs build takes quite a few lucky drops.
It's mostly an Ao100 build, though; on any other mode, you won't have time to enjoy it, before frying the mastermind.
