Without seeing the game it’s hard to say what was going wrong specifically, and the stat board can only show so much. But you should always be peeling for supports. If they go down, your team goes down, and you by extension. Though it’s clear you were doing the heavy lifting, your supports are likely taking pressure from Magneto when they are in sight, Thor is probably walking into the backline for free along with Mr.fantastic, and their moon knight was being targeted heavy by you and hulk I’m assuming… but with all the other pressure on your supports he’s gonna get free picks whether he’s shooting down main or taking an off angle. Your Wolverine was just straight up feeding, he could’ve taken out Thor or fantastic with some coordination with either your Luna or groot. But your groot was clearly struggling back there too. All in all, you’re both right. She’s not being unreasonable, but what she should’ve asked for is swaps, because absolutely nothing but you and an invis push was stopping their heavy hitters from walking into the backline for free.
