Modes are Made to be Fun/Broken
That's why they're featured and leave in a short time. These game modes are made for people who like to mix things up a bit and have a good time with the ridiculousness, whether they get stomped by an OP comp or not they're still fun(talking about myself here lol).
If you don't like how these modes are made then i'm sorry but being toxic in-game to the enemy won't change anything, just take a deep breathe and by an oracles for those shrooms.
