As far as divine power, I don't really have a problem with it. The +6 takes care of the major abuse, which is the 8 Str cleric (who point buys his way into higher stats elsewhere) then relies on Divine Power to help him in combat.
That's not Divine Power abuse.
Divine Power abuse is Polymorphing the barbarian into a Str 1 raven, who then uses his purple Ioun Stone to cast Divine Power, which grants a +17 Enhancement bonus.
You then Polymorph him into a Str 23 Troll.
23 + 17 + 4 from Rage is a 44 Strength for the duration of Divine Power...
