Spear Rogue you say, now that could be interesting.I saw some people talking about new Fighter feats. Did any other classes get additional feats, outside of class archetypes?Yes, the Avenger Class Archetype section has a little section stapled onto the end that provides two spear feats for the Rogue Ranger AND Fighter.The Level 4 feat is essentially Polearm Mastery. If you're holding a 2-handed spear, hammer, or polearm, you get into a stance that lets you treat the haft of your weapon as if it's a separate weapon, which is a 1d4 simple club weapon, has the agile and finesse traits, and benefits from fundamental runes of the main weapon. Since this counts as you holding a separate weapon, you are treated as if you are dual wielding for the purposes of feats such as Twin Takedown or Double Slice.
The Level 10 feat is basically Impossible Flurry but for 2-handers. While in the Level 4 feat stance, you can spend three actions to do 2 strikes at no MAP, one with your weapon and one with your haft, and then another 2 strikes at max MAP, one with your weapon and one with your haft.
Based on your description, I whipped up some tables showing which weapons would qualify for these feats. It's a Google doc so it's best viewed in an app designed for those.
It occurs to me that the Fighter's Fork would also qualify when in its two-handed form.
One thing to remember is that the haft only has the agile and finesse traits so a base weapon with Reach doesn't confer that to the haft meaning you either lose out on reach or don't make a haft attack.
