well osiris.sry if i've been a bit rough there.

It's just that sometimes my "rage" opens on its own :P

Well,as for the many prestige classes...You have a nice backround,honestly,for my tasle you qualify to take them.but thats up to the dm.

I rly advice you to replace battle blessing,even though your dm aprooved it.Man its just bad ,when he sees you quikening with no turn-cost 6-7-8-9 lvl spells,somethign a lvl 20 wizard can't do , he will just remove it,due to the understanding of the mistake he had comited!!& even if he is willing to allow it then only 2 things can happen.
-rest of the grp beat you up :P
`enemies will come up with similar builds,
you dont want any of these i suppose.

& as for the complication. i believe that ppl here mentioned it up because you are a cleric!even with worst domains & no prestige & just average feats you are 1 of the best classes.
try time domain(quikened spell)/undeath(extra turning) + simple prestiging & you are the god around there.
