Probably nerf all of Aug’s support stuff into the ground then give them different things like stops or knocks, support doesn’t need to mean “Hi I give you max throughput buffs that force you to bring me to keys”. I dunno, maybe get crazy and give them an AOE stun, WHOAAAA, crazy I know.
Honestly though, I think it might be time to axe Rogue. Maybe turn one of their specs into a support. Rogues act more like support in movies as well as comedy relief, having them be pure damage doesn’t even make sense, they’re rather cunning and capable of a lot more.
Take Subtlety and have it revolve around Mass Stealth. You could give them the ability to Vanish other players, kinda like how Brightwing and Tyrande can vanish people in Heroes of the Storm. It would be a survivability external, could attach anything to it, like DR or something. You could make them a Bard without being a Bard basically, maybe the first spec that pulls out a guitar or something, lol no maybe that’s a little too crazy, but Warcraft has had actual guitar animations and models for the longest time.
