I took the Vampire way to rescue Imoen is that worse then taking the shadow guild way?

Not at all. It will actually get you more items in the end, but I won't spoil the storyline for you.
Good luck!

You wont win any brownie points doing it that way.

I have a question in regards to this same topic--I'm currently playing a (highly) evil party through SoA, and my child of Bhaal dude is a fighter/mage/thief....i've already done the fighter and mage stronghold quests before, so this time around i want to do the thief one.

my question is, is it possible to get the stronghold (by doing the Mae'Var and Renal Bloodscalp sub-quest), and then still side with Bodhi after that without messing with your possession of the stronghold?

Bodhi's quest is far more involving!

And naughtier . haha ha ha ha!
