These changes impact PvE significantly more than PvP. The amount of content that will be made unplayable for certain classes and specs for PvE from the suggested changes is actually upsetting to a point that is hard to put into words. Speaking of just the two specs I play primarily, Hatred and Lightning, the removal of the saber strike dot tick from two time trouble will flat out make the spec unviable for endgame PvE content and there is no real good backup rotation other than the 6.0 rotation which is a force deficit rotation, where I end up standing still doing nothing waiting for my force to regen. The changes to lightning make it significantly less viable for fights in PvE that require lots of moving around and the same is true for the PvP application, I will be lucky to get off a full cast of HO without being stunned or interrupted.
