<<The solution I'm currently planning to prevent gaming the system is to allow feat points to go negative. So, say you spend 10 feat points as a non Heritage Bard, and buy all the Taleweaver feats and then join the Songsworn. At this point you have 15 feat points worth of feats, but only 10 points to spend. You'd be prevented from purchasing more feats until you worked off your debt, but in the long run it works out the same.

Ah. That makes sense. That's just like how you can incur TDP debt on a new character to get a head start on stats by joining multiple guilds, but can't train any stats for several circles while the debt gets caught up.
