I've sent people to ENWorld for the die rolling and text formatting. So, until those are restored, 75-80% disappointed. Speed is good. But I use forums slower than the old forums. So speed doesn't excite me.
Probably not the first to remark upon this, but since this forum now shows an uncanny resemblance to rpg.net, I guess XenForo's quest for world dominance (or at least dominating my personal user experience) is complete!
