let's talk about team responsibility.
let me say this. if you see the team needs a specific class, and nobody is playing said class, you better choose that class. it's like TF2. if the team needs a sunflower, and there isn't anyone else playing it, you better assume responsibility and pick sunflower. even if you don't like playing as a certain class and would rather play peashooter, you still need to man up and say "I don't like playing as this class, but my team needs it. I will assume responsibility and pick Citron/Chomper/Oak/Space Station/Engineer/SB/whatever.
if you are playing a class like Corn, and there are 5 other people playing Corn, and the team is losing, pick another class. because MAYBE the reason the team is losing is because there are 6 OF THE SAME CLASS! WHYYYYY! pick a defense or support class. or heck, just have a team made entirely of Space Cadet and Space Station and spam Crater Maker.
just be a proper teammate and do the objective. the shooting sucks, so the only fun you will have is doing the objective.
