I've seen three since 1992. One took just the concept, and developed organically away from it. The other, he got pissy when he found that I didn't share his view of the world with him at the center as the special snowflake. The other is a rogue in my current AL game, but at least he's being subtle about it.
Then it is not so much the concept of a Dritzzt template but a certain type of player we all run across from time to time - the "special snowflake" who always wants to shine and gets pissy if he or she doesn't? Then runs out of your campaign when the game is not a masturbatory power fantasy with your other PCs as minions, leaving you as DM with lose ends? We could say the same about someone wanting to play Legolas, Thrall, Elminster, Gandalf, or anything else as their inspiration. Separate the concept from the bad behavior.
I still think strict player control is to blame. Or, certain kinds of potentially disruptive players who could have played any other kind of class/race/style combo.
Now, if we are talking Dragonlance kender, I can completely understand. Not because of hatred of the little folk, but the whole "borrowing" err.. stealing from PCs kind of gameplay it encourages I find disruptive. And, it is the only thing I refuse in my game.
As far as the whole"Drow came from an evil society... blah, blah. Impossible. Not in my world." I don't buy . I still think some of you other grey neckbeards just don't like PCs being cool.
And by the way. DMs who do not let the players play something they like within reason really need to go the way of typewriters and VHS tapes.
I personally avoid the "control DM" fantasy stereotype that only plays levels 1-5 and only allows a narrow selection of preapproved characters in his sessions.
