My call of fire drops everything but the last 2 tremor totems. This is so I don't overwrite the staggered totems when I re-drop everything which I have a habit of doing.

The resistance totems are only marginally effective in arenas due to high spell penetration on warlocks, mages, and shaman. It may give me anywhere from 0-50 resistance in those cases. In most other PVP, especially where you see people in PVE gear, they're much more significant.
