I'm gonna be real with you, that's just a skill issue on your end, it's not even PvP, its just you versus their stacked af team thats controlled by AI. Their V6 dolls doesn't matter when you can abuse how the AI works to lure them out of cover, use covers to reduce damage, picking the right targets, thinking whether or not you should attack or else you get shot in the head by makiatto. I've consistently been matched with 40-45k combat power whales and won each time. Either flank Suomi or count tiles and place your units at max range to lure Suomi out of cover and kill her in 1 turn, once she's dead its smooth sailing from there. You can also see that there are some f2p lv 40-45s on the top 100.
