Jungle Coach - Diana S4 - Struggeling with closing out games / macro impact

Hello everyone,

I recently tried to focus on less fighting, less dying and more pushing for objectives (esp. Voids and Herald).

The games I play tend to go well in the first 15 ish minutes but then fall apart completly and i do not know what to do and how i can help my team to win.

Doesnt matter if i am ahead or not - it feels like i cant play the map at all and cant make any impact then.

Would someone have some time to go over the two games and/or i stream a ranked game and we are on discord?
