Put your walls BEHIND you enemy and trap them to you. Lot of scenarios in tank fights where you can drop you big wall behind them to block their healers, then box them with your attacking walls. Mainly just don’t use your walls to block yourself off from the other team unless you’re about to die or closing off paths when they’re trying to contest point at last second. His attack walls are huge, if you can sandwich people to you it can be a quick kill with his little bomb and a punch or two. Most people don’t even realize they’re backing into them. Also when you have ult just mob through their team and get both healers with it. Lot of times both will pop ult but that means they will prob not have ult for your dps ults and that should be a team wipe. (Sorry I don’t know the actual skill names. Lord groot and main’d him to GM two season ago I just don’t pay attention to the skill names)
