Combination of Polearm Master and Sentinel seems very apealing for my Barbarian. >:]
With cap of 12 that combo will work only on fighter and it's extremely bad on barbarian especcially due alot of reason.
As for optimisation all is simple feat at 4lvl then +2 asi in the main ability at 8 and 12 with rare exceptions.
Hoping for VHuman for an early additional feat.
Not gonna happen. There is no place for cheat in BG3.
