On the current 3*s tournament reds are not allowed, that maybe why you don’t see them.
Brienne is good.
I’ve built 3 reams of 3’s, 2 regulars 1 Atlantis, i can mix and match to most opponents.
What about levels 4/60 and up on 4 star?
Well red is not allowed in this tournament I’d say some of the best 3* heroes are red though, their attack stats are quite above average over most other 3*s.
Brienne is not a healer, she is an attack buff
She was the first green i got and i leveld her and she is awsome! once you get that buff up you will do some really good damage! still use her and the damage never disapoint me.
No idea, 4 star heroes always finished quickly enough so we never did the math on them.
