nelf by far, shadowmeld is too good. Void elf teleporting is clunky for boxing.

Shadow Priest is looking great, and you can use the turn key to group face targets, have been doing that since vanilla. Can also macro an About-Face for your whole team and the range of view for casting is completely covered. Now chasing down targets isnt going to happen, but if they are running away than you are controlling your pvp objective. Shadowmeld can help you mount quicker sometimes in an emergency.
