Since 3.2 you can now visit your shaman trainer who will give you a quest to hand in all 4 of your totems and in return you get one Totem of the Earthen Ring which counts for all 4, this totem is also deletable, an doing so will still make you able to summon your totems (as long as you have an relic lvl 54+)
