I wasn't really calling shamans OP but rather that tremor is outdated esp. with the tools a shaman has.
I think the spell I was referring to was unleash elements? or weapon? I wasn't really commenting about the amount healed but rather the usable while silinced part.
I disagree with the last part, you have both grounding(not sure what's broken about it) and windshear. If tremor was removed no other tool would need to be provided to break CC as you already have two to prevent it.
Unleash elements heals for max 5k, and with health pools over 110k now I'd hardly compare it to bauble.
Grounding is broken like spell reflect, you can have it up and still get afflicted by the next spell casted at you due to server lag or your own lag w/e. This doesn't happen with sac / swd as you are broken out of the CC once damage is directed at you rather than preventing the CC from afflicting you in the first place. Along with other benefits such as reduced DR on yourself.
