I've been looking for several spots in WG and came with a top 5 spots for the horde:
-West Workshop Graveyard (Horde control)
-Blinked (while swimming) into iceberg (Mage only, biggest spot is under the central bridge on the northren side)
-West Workshop Graveyard (Alliance control)
-Warsong Camp (Horde control, near flightmaster)
-On the arches under the West Bridge
