Since there is lack of variety of jobs especially legacy jobs I think there needs to be a legacy job that is called rammus that is based off of Rammus from league of legends.
Passive ability: takes 60% reduce damage
Has a swep/ability that when used makes rammus have 90% damage reduction and does 50% damage back to the attacker that last for like 30 seconds and has a cooldown and its visible when they have it activated.
Rammus cant use weapons other than their fists, they also are equipped with a lockpick and a keypad cracker
