I will preface this with while I believe a D/D ele mobility is okay and I can like many others make it work, but there is still room for improvement.
A little while ago I made a thread about turning RTL into a flat 40s cd instant teleport. After reading some of the responses I still believe that a change like this would be incredibly beneficial to the class because it would allow more synergy between attunements without the need to carry particular utilities (looking at you lightning flash). However some posts made very good points that D/D could stand to gain mobility, but if RTL was reverted not only would D/D gain mobility S/D would gain mobility and I’m not sure that a change like that would be balanced but then I don’t play S/D.
So outlined below is two changes that I believe would add mobility to the D/D set, smooth out a rough skill and add some synergy; along with my justifications.
Ride the Lightning: 1200 range instant teleport 40s cooldown. This would give some synergy to Churning Earth and also allow for D/D and S/D eles to get out of rough situations that might otherwise end them. This would also give us the ability to out maneuver people around vertical terrain. Which as a low armor, low health class would be greatly beneficial. Currently it is so unreliable and for the most part goes on the full 40s CD and for what it is I don’t believe for a second that it is worth that kind of cooldown.
Magnetic Grasp/Magnetic Leap: Now called Magnetic Rush, 900 range leap (function similarly to bulls rush) dazes target and immobilizes them for 2 seconds, 15 second cooldown. This one could be borderline OP because of the daze how ever I think the daze is needed because you would be getting into melee range of your target and that kind of move can be incredibly risky, the daze would allow you that second to adjust your self. This would also help fill the gap that was caused by the RTL nerf and remove a skill that just feels awkward (Magnetic Leap).
