Point buy does have odd consequences. For example, monks live off tavern brawler and also like dex and Wis. So, to do this well, you need to abuse the items of set my stat to x (gloves of dex) then respec to make that stat an 8. Earlier in the game you have to do that for strength then drink potions of strength when it matters. This is all on top of Wis for stunning fist and con so you don't die. Even leaving int and cha at 8, that is a lot of points needed.
