Support class would work, it could be more than healing, possibilities including:
- Health/armor buff
- skills to immobilize all enemies while players can regen
- Heal over time like in SL
- Summon allied grunts to serve as meatshields
- skill to taunt enemies to an area away from players
Just a few things I thought of in couple of minutes, I am sure full time game developers could come up with even more.
I definitely agree with you as I said the entire game is platinum run essentially
Sorry that AL players are more stupid, but what do you expect when they are chosing to play a worse game in the first place.
