1st Fix Fighter!! Why is it the worst martial class? If nothing else use the Soldier class from Starfinder as inspiration. Also, please use Unchained Rogue and Monks as what your new versions will be based on, please.
2) While I like the idea of simpler system, like what Starfinder has, please don't go to overly simple like 5ed.
3)Skills need help but I don't like the idea of Skills acting as your initiative, especially if they are as easy to cheese as they use to be.
4) I am happy to help playtest, feel that was what Starfinder needed to help fix some of the issues it has.
5) The proficiency idea I will have to see what it is. If it is like what Starfinder does, I won't mind, especially for weapon focus (and versatile focus) and weapon specialization (and versatile specialization).
Honestly, with having every AP since Kingmaker, I'm not sure how far into the new system I will go with you guys, but am willing to help debug the playtest to make it the best it can be.
