The DM is the type to use a wide scale of mobs to fight the party so that there's always a challenge, he does however have a tendency to upscale encounters. (example: we handled a young adult green dragon pretty easily at lvl 3, next encounter had us fighting a worg, an owl bear and quite a decent amount of bugbears).
With what all of you have been saying HAM sounds like the best option, I'll trade in my parry maneuver for commanders strike to boost the parties damage output as well.
Dueling fighting style at lvl 2 pala has my preference over protection, since generally I'm the only one on the frontlines anyway and I'd like to be able to do at least a bit of damage myself incase it's really needed.
