I just wanted to respond to this from the other thread:
You've read my CO Diary on the Totemist, right? Imagine the fight against that White Dragon with the entire party active in it. Now imagine the DM having the dragon do something smart, like strafing breath weapons or spellcasting on the wing. We had no spellcasters in our group, no magic items (until Eisin started kicking ass and taking names), and were up against a CR 11 Dragon. Oh, and no one in the group had flight.
SCREWED!
Granted, our DM was an idiot and I managed to slay the damn thing with ease (even if it was a fluke), but that's besides the point. You need spellcasting against enemies like that just to get around easily.
I'm too lazy to embed the quotes manually, but I said that the game should run normally assuming the DM adjusts for the lack of PC magic. A DM tossing a smart (semi-optimized) dragon at a magic-less party needs to adjust the power of that dragon or at least adjust the surroundings. Same thing if NPCs and BBEGs can be full casters but the PCs can't. That's just poor management otherwise.
After a few discussions, I have narrowed down the restrictions.
-No classes with spellcasting progressions that get more than 4th level spells
I think 6th with limited lists might even be reasonable. This would allow the Bard, and a few of the oddball PrCs like Suel Arcanamach and Knight of the Weave.
I think one of the main problem with casters is the cherry picking of spells (or blanket access to everything). We're so used to the CO mindset that everything and anything is available, that there are magic marts with all available spells and scrolls, etc. I believe that the DM should be enforcing limitations on spell choice. That's just my little rant/aside though.
Oh, I'm also interested in playing, though that's kind of moot without a DM.
