1: Realize that the skill gap between low plat players and high plat players is very slim. All these people have good game sense and good technical ability.*

*(non-smurf, no stat manipulation like carrying or stacking with higher tier players)

2: Understand that communication is key. If you mad, you don't make any ♥♥♥♥♥♥♥ sense.

3: The thing that primarily differentiates a winning plat game from a losing one is not generally based on game sense or technical ability, it comes down to which team made more cumulative mistakes during gameplay.*

*in diamond play and on the high limits of the plat elo scale, mistakes during setup start counting much more against the team.

Toxicity

That's it.

Don't be toxic. When you're toxic, your team has to use the remaining cornflake of brainpower left to actually process the ♥♥♥♥ you're saying, and this causes error.

Bonus points:
Don't peek dumb angles
Wait for attackers to actually try to push site instead of feeding frags

Welcome to diamond, where you actually have to start worrying about setup and strategy
