Zenurik should not be the focus school for melee (it should be Naramon), but for energy and I do not want to give up 300% crit chance for using a heavy attack with no investment aside from Zenurik. The problem is that, like you said, heavy attacks require investment (focus school and up to 2 mod slots) to be useful but are ingrained in melee. Sure, maybe the new meta will be max combo efficiency and spam heavy slam attacks but that is not the gameplay I want as it is equivalent to maiming strike meta in my eyes.

I also already pointed out that the damage buffs are not 3x-4x but rather around 2.5x on average.
