Blue
Ravenous Bugblatter Beast of Traal
So perhaps something like this:
v.Human feat: Polearm Master
3rd level Maneuvers: Precision Attack, Pushing Attack, Trip Attack
4th level: Sentinel
6th level: +2 Str.
8th level: GWM or +2 Str.
12th level: whichever I didn't take at 8th
14th level: Tough
Don't lock yourself in. If you see that your party is good on buffing (or debuffing) then between that and Precision Attack go for GWM @ 4th. If not, see the types of terrain your DM likes - wide open, tight, complex, full of hazards - and if justified pick up Sentinel. If you're missing a lot or neither of the others are true, go +2 STR. You're not advancing your character in a vaccuum, but rather at a specific table. Play to that.
