Quarterstaff Mastery Feat

[Kane0]

If you take the first to points (+1 to hit, +1 average damage) that's effectively the same as +2 to your attack stat which is what an ASI gives you, so this goes over the supposed balance point.
The reaction and bonus action benefits seem a little too clunky as well, especially since you will probably want to have them both active as much as possible which will eat into your actions heavily.
I'd recommend taking out one bullet point anyways, as most other feats feature 2-3 parts to them.

May I suggest:
- Increase of damage die to d8/d10, or even d10/d12
- Gain reach when using a quarterstaff (no action required)
- As a bonus action gain +1 AC until the start of your next turn

And while you're at it make sure to swap 'quarterstaff' with 'spear' in Polearm Mastery.
