Tremor Totems need to reduce their pulse interval to 1 second, or become like every other buff totem and apply a continuous aura.
I've been pvp-ing with my enhancement shaman and have serious issues with the tremor totem only pulsing every 3 seconds. Often I get feared completely out of its radius before the pulse goes off - in spite of being specced for increased totem radius. Not to mention the totem is instantly destroyed if I am facing someone competent.
So I am spamming a worthless spell in exclusion to spells that actually do something before they are destroyed. Even if Tremor Totem were indestructible, it would still use that vital earth-totem slot. Since it robs us of other functionality, it needs to consistently work... but often it fails at the job it's specifically designed to do.
All DPS classes need some remedy, however imperfect, against fear. Rogues have stealth, stuns, and Cloak of Shadows. Warriors can toggle fear immunity for a significant duration and subsequently intercept if need be. Druids have stealth, cat stuns and bear intercept. We Shamans are stuck with Tremor Totem, which is ok for PvE but hopelessly inadequate for PvP.
Is Blizzard looking at this? Sorry if this has been covered elsewhere. I'm sure others have complained but I couldn't find their posts.
