Bummer about starting at first level, but I understand. If it makes sense for the story and setting, I can roll with it.

I used to be a big fan of psionics (especially soul knife, which sucks but is fun to play), but over the years I find them to be underwhelming. 

If anything, the only thing I've banned from play when I ran in the past is true name magic (from tome of magic), on the account that it's terribly done and shouldn't exist as a separate playable magic system.  Sure, binding, shadow magic, incarnum, and book of 9 swords are almost as badly done, but they're still playable. And in some cases, quite fun.

Don't worry about dice rolling. If anything, I'll roll every time as needed without a second thought. I'm used to PbP DnD.
