Same tbh. Been playing for over a decade. I'm an Infil main, so I got that down in its various forms (as VS). I'm alright with Engi and Medic. And that's about it. I'm bad at LA and I definitely can't play Heavy. Weird, I know.
Busses I'm fine with, Gals and Harasser I'm OK. Skyguard lightning I'm pretty decent at though.
