Note : This is ONLY for Dalaran Sewers.
When you're in the sewers and you first come out against most teams my DK will run strait across to go beat up one of their players.
EVERY Shaman hates totem stomping locks/dk's so the idea is to drop a tremor/grounding totem INSIDE the middle where the falling water comes down, the pets can't get in the middle to stomp you
We just beat a Pally/Lock (counter) because they couldn't get fears off. as long as you're up top(and some on bottom) you can always get reached by tremor even though its best to hug it.
Good luck.
