Arena Passive Fights

I am so sick and tired of fighting the Thanos & Kang team in arena. They’re so passive that it drives me up the wall. You have to damn near beg them to throw a special and when you think they won’t throw any at all BOOM they hit you with a sp3 and you are dead. I can’t stand it. How is this any fun to players? Not to mention their specials are strong enough to clear 98% health, but if I used the exact same champ, with the exact same special, I barely scratch the surface. For the love of God, Somebody fix this. How many years have to go by before you realize that these mechanics aren’t fair in the slightest? Where Kabam Mike when you need him? I need answers.
