EIN was the only cool monk only T6 experience- after your change its just another instant death effect, where DC-casters are mostly better in every situation.
It should not be so hard for a experienced DEVteam to fight the lag of 20 monsters in one room with 6 characters because of EIN. You are also able to provide a solution in raids like the endfight of legendary shroud where waves of monsters coming from every side. Instead your only solution is to nerf this ability down to just another death effect even less effective then wail of the banshee (available at Lv17) or implosion (also available at Lv17).
I understand, that the charging is somewhat clonky but much much better if you have a fantastic epic moment result instead of just another death effect.
For me the destiny will derange from a fantastic epic moment to just another death effect and all your other arguments will not change that endresult, sorry.
Best regards
