On my struggle to decide on either rolling mage or elemental shaman (which has been on for 1 week and is still ongoing...) i have especially been looking at the different rotations offered by the different specs and came to following conclusion: fire/frost and elemental are not really engaging! What they basically break down to is spamming a filler spell until something procs and then use the proc.
Now, especially for Elemental, i have been thinking about how you could tweak the rotation a bit by adding a simple mechanic without drastically changing everything. And this is what i came up with:
I would have really loved to get sth. like the eclipse mechanic (e.g. elemental atunement) with maybe an additional earth-spell with cast-time. But as balance druids already stole this from us, i thought about sth. quite the opposite: You try to maintain a certain level of "grounding", which will decrease the cast time of your lightning-bolt/chain-lightning. "Grounding'" will get smaller by casting said lightning bolt/chain lightning, and gets bigger by using earth shock. You want to maintain a grounding level as high as possible.
The basic idea is that by throwing lightning you charge up yourself and therefore it gets harder to build up the electric tension needed to evoke it again.
So, while this will not change that much about our rotation, you might end up using your fulmination stacks earlier than after stacking up to 8-9 in order to maintain a certain level of grounding. Of course, looking at how fast fulmination stacks built up right now, this might need some tweaking of the proc chances etc.
I first thought about giving bonus damage to the lightning spells depending on grounding, but thought that this would work counterproductively to our mastery.
My goal with this is not necessarily to add further complexity to given rotations, but to include some "thinking" component on when to use certain spells etc. From this perspective i think that e.g. arcane is a very cool spec, as you have to decide on when to burn and when to conserve etc, although it is definitely really simple just considerung the amount of buttons you míght have to press.
I think that the linear damage progression from those "stupid" rotations like fire/frost/ele etc. are simply not as engaging as the non-linear rotations from balance/arcance and maybe the upcoming new mechanics for warlocks. I would really like to see something new in this respect for the other specs.
So, what do you think? Would be grateful for any opinions and also other ideas for new class mechanics!
