its a bit too soon to call anything a dps nerf, which it really isnt. the kjc change will not change much of your current dps as you're mostly doing MG while moving anyway, and worst case you'll MG a bit while moving during execution the loss is minor and being able to move 150% base movement with burning rush will be very fun atleast and it will actually cause you to get to a safe spot much faster, further reducing your dps loss. the survivability nerf was justified, we barely had to worry about anything in pve.
