Need to know if I should improve my gameplay with ball

Hello everyone, I play on Xbox (with keyboard and mouse) my user is PtitZgeg and I played ball in these 2 game.

My ideal gameplay is to play extremely aggressive with my team and not let the enemy team breath, always have pressure against them, especially supports or squishies.

For these 2 game I feel like I've been more focused on tanks than support and played way too aggressive to the point my team couldn't follow I think. I have decent mobility and try to harass the enemy team but I think it's not enough, any tips or criticism will be greatly appreciated, don't hesitate to be harsh.

I'll answer any question if needed.

Thank you for reading
