Well, as far as I'm concerned, after working the numbers and playing with the possibilities for a couple of hours, I'm going to give this PrC a big, fat
"Not in MY campaign!" and let it go at that.
The single biggest reason? It doesn't actually turn out to be as ridiculously overpowered as I thought it would. But it
does turn out to be overpowered
just enough that many (if not a majority) players with spellcasters are going to want to take it.
Which leads to the biggest problem, IME - blurred and overstepped 'roles' in a party.
Consider if you have a party with the classic "1 rogue, 1 fighter, 1 cleric, 1 mage" in your group. Now consider what happens once the mage, at 4th level, multiclasses to cleric. Then at 7th level, takes Mystic Theurge.
From 4th level on, the guy playing the cleric
only has a few spells that the other character doesn't. And for the rest of the campaign, he'll only
ever be able to do a very, very few things that the mage/theurge can't. That's
assuming for whatever reason that the cleric player doesn't decide to do the exact same thing - and I don't have to enumerate the problems if he does.
This may seem like a "so what?" kind of issue to some. But I guarantee: in the majority of groups where this situation comes up, it's gonna cause problems.
Besides, as a second place problem - at higher levels, the Theurge becomes an absolute terror as a support caster. And there are enough headaches with excessive support casting IME anyways. So, I'd rather not throw into play a way to compound the problem, thank you anyways...
At least I'll be able to warn my senior DM and his/my players that this PrC won't be an option before the book ever comes out. Thanks, WotC!
