Lets say a team fight just finished and Cait remains on their enemy team with too much health for your team to handle (2people left on your team) you are vayne and you also have Lee sin with you. So as you run back cait decides to ult you, but you're running exactly parallel to lee sin so right before the ult hits, you flash right in front of him and he dies and you live. Is it justified since you're the ADC?
I wouldn't do it in a ranked game but I have done things like this in normals just for the laugh. On Mundo the other day I was hitting their mid inhib while a couple of guys on my team were at the right inhib about to kill an enemy. So I flashed three feet to the right and stole that kill with a cleaver. Felt good.
Overused memes disqualify you from conversing with me.
Quite a lot of potential factors there, but overall it wasn't too kind a move to make in soloq, because no matter the minor gain you may have made by living, you almost certainly pissed off your team mate.
Potentially a good decision though.
