You don ' t need to play every hero well , but you should know how to play every hero . If you know the mechanics and basic strategy of every hero then you can better understand how to counter them . Reading about countering certain heroes isn ' t as effective as experiencing being countered . For example you ' ll notice that if you play Winston and you encounter a reaper you get melted down super quickly . You can watch the killcam and see exactly what he ' s doing to melt you . Knowing how to play every hero well is a plus though , and IMO makes the game more fun . There ' s more variety and you can analyze what heroes the other team are using and counter them . <| sep |> I assume you are a beginner too . The Take The Camp SP Scenario from Steam was a really good next step for me after the builtin stuff . It helped me work on coverconcealment and using the stance modifier . As always the AI are deadly accurate and a simple scenario helps before diving into more complex ones and getting shredded by AI . rrnThere is a second mission in the series now called Take The Airfield . I haven ' t tried it but mission # 1 was the best next step for me after the built in stuff . rrnWhen I was at your stage a few months back , friends took me right onto Invade Annex MP servers and it was a bad experience . No two players wore the same uniform and many people were flanking and coming back facing you so it was difficult to tell friend from foe . I was lost and got killed over and over because I didn ' t want to risk a TK and get banned .
