If you ping your teleport, split and never use it when a fight happens.
...Why did you even suggest it in the first place. The enemy are looking for a opportunity to engage since it is a 4v5 with objectives at stake. But your teleport is the thing that is barely preventing it from happening. And if you happen to not make it, please keep pushing since its already a lost cause. If you do this multiple times costing the game you are being untrustworthy.
Also. Don't DARE try returning to the base by damn foot and get caught 1v5 after that without taking anything.
