30k dps single target in non gimmick fights (where u get a damage modifier) will not be that odd in 4.2. I was able to pull several times 25k dps versus 'tank & spank' fights bosses in current tier as ele shaman without dark intent or focus magic. So with new 2p setbonus (fire ele always up), and new stats from gear that 30k seems not out of control as a number in itself.
The 4p T12 mechanic in itself is not really that much of a dps increase because of the way how instant spells and queuing your next spell works . The current problem is that you can get a lava surge proc while you are casting lava burst, which is basically a waste. The new bonus should address this the way I understood since it will be 'saved' till your lava burst cast is finished, and then you can cast an instant. The 2p bonus is much stronger in terms of dps. So actually it's far from OP.
The Fire nova mechanic is actually really poor and cumbersome, it takes ages to ram up your dots; and adds usually don't live long enough to benefit from it. The only fights in the current tier where it works to some extend are maloriak hc black phase adds and halfus hc. And obviously on some trash. But then again other class have way better aoe to call ele shamans aoe OP.
