As someone playing a Drow, can I just add that I don't give a damn if I can level to 18 or 20? It's not like I'm playing my rogue for uber powergame l33tness, I'm playing it because I find it *fun*. It would probably be nice to be able to level for 2 more levels, but meh, who cares? If you're playing the server to RP (like you should be doing) it doesn't really matter. This is only gonna upset the power gamers... who I don't much care for anyway.
(By the way, someone mentioned darkness + sneak attacks = overpowered - it's bugged, the target is treated as concealed 50% and gets bonuses as if it was an invisible creature. Found that out the hard, painful way.)
