i think this would be a fun class, kind the opposite of the berserker. berserker rushes otu and kicks zed, riot class would be a support class, i would imagaine they would be able to hold shield in one hand and pistol in the other, perks should include being able to attract zed to them and not teammates, damage reduction, higher sheild durabilty, better armor or more of it, and special should be sheild bash that woould stun a zed(s). this would make it so the "tank" would attract zed and be able to hold them off but not be able to kill them too effectivly. maybe make them to be able to carry less weight.if its going to be a damage taker, it should be able to take damage but not deal it out as well as its getting. but i like this idea +1
