It becomes more relevant as games strive further from fast and numerous respawns. Q3 and the likes provided you with a lot of gunplay practice while CS classic matches and moreso BR games do not. It becomes harder to become competitive without such aids when you have a couple of shooting encounters per match\game while they become more decisive of your lose\win this time.

I don't like the idea of that at all, so I generally skipped games with that model.
