Well I hope the fans of evil paths get what they want. But I also hope they get it in a way that doesn't mess with the heroic path. The problem I have with most evil paths plots is the creation of viable evil path sometimes comes at the detriment to the heroic one.

The FR are a heroic setting at the stories tend to be about heroes saving the day. The path of villian should be there but the writers shouldn't be forced to make the hero's story / villians story equally appealing. Sometimes when you try to please everyone you please no one. Anyone remember John Stewart / Steven Colbert's rally for "sanity and/or fear"?

To me, the evil path seems fine. The absolute has power, that power is based in Moonrise towers and the drow is you key to unlocking that power. Astarian gets it -- you need to find out how to get the power without the cost. Check out his dialogue after finding that true soul who died from his owlbear inflicted wounds. The evil MC is in better place than the fools he has deal with -- the brainwashed cultists aren't are aware of what's happening while you are. Sounds like an opportunity that can be exploited.
