its funny how all they did to iso(something that affects gameplay badly) was just give him the shield before the round, due to this man just becoming unkillable by an op or any other gun in the game.
The worst part about iso's shield is not the fact that he gets it at the start. its the fact that even one-shot ults like Raze and chamber ults cant kill him and just break shield. His shield is fine If they fix the part about the ults he would be far less broken.
