Hi again.
Back in 3.5's "Unearthed Arcana", there were optional rules on how to deal with metamagic feats.
Is there anything like this in PF?
I am asking because I (still) think the standard rules are no good.
(I don't want to start an "argue-thread" about those rules, so please don't...)
Nope, there aren't any. It seems those feats are only really good when building around certain spells or types of spells.
