Well I'm an Overwatch fan and while I haven't been playing CS in a long, long time due to the times when in almost every server I played on was a bunch of wankers fun players sitting somewhere with an AWP and shooting my face the same second I peeked behind a corner.

Then I had to sit and wait for next round to start.

However it was really fun when I managed to avoid these, so I've been a fan of competitive playing.

Overwatch is great for most people, even those who don't have energy drink boosted reflexes and grand aiming skills. In Overwatch you can play well (with some characters) even if you truly suck at aiming! That's how I started to play Overwatch, with D.va, Mercy and Winston.

However playing more gives confidence and when rest of the team sucks (usually below platinum level, sometimes on plat or above) I've been going for DPS heroes too. Being calm is the key, as taught by the movie Unforgiven:
"Look son, being a good shot, being quick with a pistol, that don't do no harm, but it don't mean much next to being cool-headed. A man who will keep his head and not get rattled under fire, like as not, he'll kill ya. It ain't so easy to shoot a man anyhow, especially if the son-of-a-bitch is shootin' back at you."
