Okay hear me out before you guys go "but Shaman is awesome", many of our abilities are basically differently named abilities other classes have also. Except often times worse, less reliable, more wonky and with more hindrances.
Take Stone Bulwark for example, it's basically a copy of Ice Barrier or a PW:S shield. Except it's tied to a totem thus it could be killed, if that was even necessary. It doesn't give you the shield immediatly but slowly over time, usually doing little good because it shields for less than auto hits of both mobs and players do in damage aswell as requiring you to stay in the vicinity.
Hex, it's one of the few non spammable CC's, it also stands out because the player in question still gets to control his character thus can run behind pillars, can be countered by DPS speccs, while it doesn't heal the target that usually makes little difference and it also breaks almost immediatly, at times even from the shaman mastery itself. It's a worse version of Sheep.
Capacitor totem, my personal favorite. It's a far worse version of Shadowfury and even leg sweep is overall superior to it. It takes 5 seconds to actually come into effect, it has to be placed on the ground forcing you to stay in the vicinity unless you take another ability solely to make it a slightly less far worse shadowfury, it can actually be killed by any opponent with half a brain.
The list goes on. Large parts of the shaman kit consist of abilities other classes have aswell, except usually worse. It's as if Blizzard just copies other classes abilities, then nerfs them slightly to make them more "shamanish" and calls it a day. what gives?
