Hawkeye’s sonic arrow upgrades can spawn a wall to stop big ultron bots annoying dashes and it applies a weakness effect that stacks infinite. With good attack speed and lower abilities cooldown you’ll have no problem. Early games hard. 

Hulk’s splash and movement is just nuts, hulks the strongest and easiest way to win. 

Witches damage is good just not hulk or Hawkeye it’s not even close. Her ult and movements clutch if the team gets swiped. 

Damage is good, his movement is crazy he’ll almost never die and give the team infinite respawns 

Thor is a really sweaty character, he works but you have to understand his new playstyle but you’ll be dying a lot and it feels like you can’t really avoid it. 

Window is pitiful, no piecing shot or aoe and her damage is really mediocre. Really hard to win with widow unless you have a carry. 

Captain America is not viable in hard mode at all, big boys bully him and he’s good in swarms but everyone is. He just gets one shot too much and really struggles doing anything of value. If his aoe punches didn’t lock him and force him closer to an enemy he’s be decent and more viable.

Hope this helps whoever is struggling with this new gamemode. 

New pve mode. hero’s to use if your struggling and my opinion on them.
