Pro play, competitive play, tournaments, leagues

I am a returning player after playing for 9 years starting on Xbox. I am now a plat pc player currently trying a new sensitivity and playing regularly in evenings apart from Fridays and Saturdays. I am looking to find a non toxic team that can help me improve, I have a speech impediment but it does not affect me or my communication much at all. I can play most roles but enjoy buck and jackal on attack and operators like vigil on defence. I am happy to be versatile whenever needed though!
