Bronze problems

Have my wins are because the enemy team doesn't know how to end a game. Like we will be getting killed but end up winning from a split push champion

Example:

Just played as Fiora (top) Yasuo (mid) Yi(jungle) and had a jinx (adc)

This team comp should rarely win games as we pretty much get killed in teamfights if behind. Their Graves (top) was nicely fed by yasuo, yi and I. It was an easy win for them if he just kept stomping the top lane until they grouped but like most bronze players he roamed from about 12 minutes and never came back to lane until I was their inhib. Moral of story if youre killing a lane just keep killing them why change something if its working.

Also fiora is pretty broken for split pushing. I fed and was still able to destroy 3 top towers, the inhib, both nexus towers, and the nexus. (4 consecutive split pushes, idk how they didn't see my going after the second one)
