I am something of a warlock junky ( 2 x alliance lv 60 pre TBC locks retired + my old main lv 70 horde lock), and now my tri box team is preist + 2 x locks. I also ran a lv 29 twink for fun in WSG for a while.

The build below is (imho) the best lv 29 twink build u can get for a warlock, and 3 of them running together would be downright frightening.

key talents -
3/3 improved imp + 1/2 improved firebolt - turns yr imps into rapid fire machine gunners and gives improved stam buff 5/5 improved corruption - obviously - because every lock wants instant dots
Shadowburn - for burst damage - shard farming can be a pain in bgs though
