Don't try to be smart by just saying the basics of every MMO, even knowing that any other MMO doesn't have such an spammable disable to the player as DBO does.
I've been outside rp2, the three towers with 1 ultra each one, and you just cannot kill the fckng tigers, the KD literally has no cooldown, I was taking 1 super by 1 to kill the ultra and i had to htb the supers, use the rp duration stun and hope to crit those bastards, because as soon as they were free I would not get up. Pretty annoying that if you are inside RP2 and you just need to deliver quests youll have to kill every mob again because if not you would die by just dashing away.
Try to go to RP1 to the robots part killing 1 by 1 but the ''Calls for help'' will get you killed. You just can't solo most of the game, unless you are a lvl 70 doing ud1.
Mobs NEED a cooldown for their skills, and they dont have one, that's a basic. Almost stuns get diminished, but KD's? lmao
