Mechanics of course depend on the map and meta. However, you cant really go into a 16 player game and expect to get the spot you want. Both backline and front line should be working non-stop and both have a lot to do. It is a sweaty game.

Paying for t2 that is usally a noob mistake. High OS play rarely asks, or has a meta for who pay to run specific plays.

One of My favorite 40 OS streamers leaves every losing game asking what they could have done better, which I think is a good mentality.
