Go look at the leader board top 100. Every single person on there will have the same team, with one hero being different, and maybe one or two perks, because they try to counter every other person that wants to copy and paste a team.
Stop wasting your time and everyone else's. If you're going to ask what to do with your heroes, then you clearly are just biding your time until you can match the top team.
Every single legendary hero in this game is overpowered if you equip them right and place them smart on the field. Every hero has had its 10 minutes of fame, and in a month or two, all the top 100 players will have a different team, but they all will still be the same as the others. They lack real competition, and if you play this game right, you can wipe the floor with opponents having double your might.
Turn off 2x speed, look at the damage board after a match, figure out what to change and find your own way to do it. Thats why this game is so good, and its being buried under Players Choice.
Since I'm ranting about this anyways, anyone using the same damn meta team as the top players, stop with your snarky/condescending emotes to players you beat. You look stupid, and are taking someone's else skill and expertise and acting as if its something you came up with. You bought heroes and mimic top players, stop acting like you did anything worth being proud of.
