I never said that spellcasting advancement is a bad thing, just a 10/10 of you're giving out class features at every level. I've played in all kinds of games and it's never been being weaker that's made me feel underpowered or useless so much as other players being self important. Thus, I honestly don't care if a class is powerful, so much as whether it has a really good angle to play from in the roleplaying sections.
I'm not planning on budging from the "'more is better' is bad design in a nutshell" stance but i'm happy enough to back down if there is a decent play reason other than "it would be underpowered otherwise" put on the table for each case.
7-8/10 spellcasting and i wouldn't blink, just not a 10/10, but i'm not really clear why it was a specifically spellcasting prestige class anyway. The musty self importance inherent in a lot of spellcasting class concepts doesn't lend itself well to depravity [shrug].
