So seems that some change is coming in 1 way shape or form in 5.4. From reading it seems that there gripe is that they dont want us doing our full max dps rotation all of the time but they dont mind us doing dps on the move.
KJC - maybe remove/reduce the speed reduction
destro - allow incinerate to be cast whilst moving, allows dps but not max, also have conflag when off cd then and generates secondary resourse in embers. sub 20% you switch to shadowburn anyway which is instant cast.
demo - shadowbolt, again allows dps on the move whilst not max you generate fury and you have the option of meta for movment aswell.
Affliction - drainsoul. Allows dps on the move whilst not max. Allows you to generate secondary resource in shards and the excecute would remain allowing you to move. You would also have the option to refresh agony/corruption if needed or get procs.
this would allow the playstyle to remain the same more or less, allows us to move without massive changes.
MF - have it effect all aoe except probably voidray, and have it only effect initial damage and not roll your dots on it ie. Immolate FNB and soulburn SoC, voidray corruption.
i would rather no change but i feel something is coming whetber we like it or not.
