Little surprised how.open you are to 3rd party materials(bug thumbs up as a fan of dreamscared press and new paths) but closed to races of ten points or less from the ARG. Though you explained that.
I would be really turned off by the idea that I cannot buy what I want within reason. I am not exaggerating when I say 99% of items I see in adventures are not the gear i want for that PC. I think a reasonable.guideline is the freedom to purchase any item as long as it's value is less then half total gear expected for the wealth by level table on p. 399.
Good to mention excessive cheese should.be discouraged but I would suggest yu go further by mentioning all such items you know and add that the list will be expaned as cases develop.
By eliminating combat exp & 13 int, you are envourageing massive str/dex/con as the players essentially have an extra 3 or extra 7 point buy when dumping to int 7. The brawler somewhat gets tnis but they are mostly expected to use close weapons group, not 2 handed wrapons for even mire bonus damage.
