Agreed. We're really missing Polearm Master to round out the big DPS boosting weapon skills. We got all these nice spears and polearms and no feat to use them! Sharpshooter too for ranged builds to compete with melee.
Resilient would also be fantastic so I don't feel so bad leaving a single odd attribute point in my list. Seems like a low hanging fruit as far as programming too. No new animations or anything.
Warcaster would also be huge for all our melee Gish needs. My melee rangers especially need this so they don't lose Hunter's Mark after a single round every single fight.
