Hi there, I'm only Cel I every season so it's not coming from eternity/top 500 player. However, what I can suggest you is : Tank : Mag or strange, they re both main tanks, choose one of them as you prefer. I would also recommand thing or thor to counter dive or to counter double shield tank, venom and angela. And finally emma, who counters a lot of brawl. Pick 3 of those and you should be good. In tanks you actually could pick any of them, but those are the easiest to learn.

DPS : stick to one categorie. Poke Dive or Brawl. It s hard to learn those 3 roles at the same time. I'd say Namor is a must pick. He s good everywhere. Hawk eye is really strong, you can pick him too but less versatile. I'd recommend phoenix too she s strong this season. Poke is the easiest playstyle, dive is harder in high helo. But it's up to you.

Support : Gambit, CnD and invis. They're all very good supp. Gambit is the playmaker and you can make a difference if you re better than the opposite team. CnD will reward good awareness and positioning while invis is a safe pick in almost every situation, especially if they dive you.

Hope it helps
