Wtf heavy is hard, you can get away with a lot of stuff in pubs, but in comp you need game sense. Knowing when to push when to hold, sniff out spy's, be weary of sniper spy demo sentry placement, understand that your gonna be taking a lot of focus, your not gonna be the one dealing the most damage in teamfights but rather cleanup when the demo is done doing his demo thing. and a lot more. Heavy is slow, and big. His tankiness is his biggest strong point, but he his shit on his own, a good scouts soldier demo even pyro can kite him 1 v 1 and win. Just because a heavy is good in pubs mean nothing in 9v9 or 6v6 he can be damn near useless. Even if he is considered easy
holding m1 on people isnt hardSo medic is the 3rd easiest class?
