It's better to design around making your character decisions matter, rather than respec... However, if you're gonna throw in retarded bugs like Bloodline abilities that don't even do anything, and depart from the source material so much that even Pathfinder vets are confused...
Well, I still don't think respec is a good idea, but I can understand someone being frustrated that they picked a feat that doesn't even work properly.
For example, the Madness domain has an ability that doesn't even do anything at the moment. You literally click and your character just stands there and then looks up like 'what do??'.
But yeah, respec isn't really the answer. Feat retraining (at cost) could be reasonable, since it's in Pathfinder PnP anyway.
You know what's actually missing from this game, especially since it's so fucking bugged?
The developer console.
I have no idea what they were thinking, removing that in a game that absolutely could've used one just for fixing issues such as starting/stopping quests, teleporting the party, adding/removing ability scores/skills/feats for testing purposes, etc., etc., etc.
