Vengeance Juggernub tries his carnage marauderp for a day, beats somebody in a duel and decides it is perfectly fine Only scrubs eat the first gore rotation.
My issues with Carnage:
-Easy to counter
-Easy to counter
-Easy to counter
-Very poor proc system
-The Undying Rage nerf
All classes can counter gore with multiple abilities. Only classes with accuracy/damage debuff cool downs can counter a jug with its stun/knock back immunity (I don't feel some form of stun & knock back immunity is the answer).
I suggest getting a gear set and trying your luck in solo ranked. It is very frustrating to lose a solo ranked match because your cool downs and escapes are drastically inferior to your opponents (Yes other classes have this same issue not just Maras ).
