People seem to have a hard time grasping that marauders are melee, medium armour, in carnage/anni they only have one real gap closer (you can say force camo, but using it to initiate against anything save agents is stupid) so that basically implies that a knockback would **** up maras pretty badly.
People just need to learn how to use their abilities, it's not like undying rage gives CC immunity, and slows isn't affected by the resolve, neither is knockback.
I do agree that mara's force camo needs a 15-30 sec cooldown increase, as mentioned earlier.
But depriving maras of their survivability is just destroying the class as a whole. It's like removing cover from snipers.
Except you have the best surv of any class while also having the 2nd highest dps of any class (close behind PTs). But unlike maras, PTs don't have a billion def cds, so their dps is ok because they drop quickly. They're essentially glass cannons.
Maras are adamantium cannons. Not cool.
