2-3) duh, if ur an npc that only uses vandal/sheriff then u arent helping your team in a lot of scenarios
4) Yes because ur fucked if ur jett doesnt know what hes doing and all of your team gets stuck in the chokepoint
5) 1v1s are not 50/50 if you play it smart, pretty sure i had above 60% wr in every act i played even when i was a dogshit player
