Successfully countered a 4-man gank, was ahead by four kills, but still lost first tower

Which snowballed the game into an unwinnable clusterfuck, because the first tower is so fucking game breaking this season.

I was 2-1-1 Lux. I roamed bottom to help out, and fended off a 4-man gank, as the enemy jungle was there and the enemy top teleported as I arrived. We got a double kill on the jungle and top, then went to push for the first tower. The enemy ADC almost died and had to recall. As we're pushing the tower, the enemy top (who was 3-1) returned to bottom lane, and we had to back off before we could take it.

During this entire clusterfuck, our top and jungle were both at top lane, where the enemy mid was holding the lane. The tower was at about 18% health. For some reason, both of them decided that diving Orianna was more important than the first tower. They tried to dive her and she got a double kill.

Enemy team then got first tower gold on bottom, and the advantage snowballed into loss of dragon, complete loss of jungle control, and three more towers. Even though we were equal on kills for the entire game, the first tower snowballing into more objectives put them so far ahead that the game was completely over.

One fucking misplay by two players on my team cost us the entire game around 8 minutes. This is not in any way okay. This bullshit is happening in 2/3 games.

This is stupid as fuck. The game has reached a state where the only thing that matters is which team gets the first tower. This bullshit needs to be fixed.
