Huge focus on support tactics. Get good at using your Tag Along and all the perks that come with it. Do not travel alone except to push a lane, since your job is to get your team fed! Core idea of this build is to save a very low health team-mate, which in turn allows them to get kills or escape. Barrier acts as a buffer that guarantees they live long enough for the insane amount of heals to go through, turning the fight around. Don't forget you can Tag Along between multiple team-mates!
