Pardon my attempt to actually answer this seriously, altough i do enjoy the rampant "comedy" going around ^_^
Personally i'd say the "best" class for nightelfs is druid, rogue and/or warrior. This because of their racial +1% dodge bonus and the added stealth from shadowmeld to rogues and druids.
But really, do whatever you want, just be warned NE priest racial spells suck <_<
