The remake system
The remake system should not allow people to remake after the first blood. I heard that they changed it because people would dive to get the first blood to disable the remake option but this is easily avoidable.
If people see that someone is afk they just shouldn't mention it and or stay in base with them until they remake, it shouldn't be a free chance for people to see if the game is going to go well or not.
As an example I just had a game where we got 3 legit kills before the enemies remaked and they only decided to do the remake because it went south for them.
