This is where the player vs player element comes in of class MU and knowing your fights 🙀
Dps (most important player(s) in lobby) / node anchor (loser training golem holding fullcap/contesting decaps in TF or the home/far 1v1) / support (waterboy resetting teamfight dps)
Perfect world you have 3 dps that synergize well with eachother for the task of 4v4 teamfights and general +1 roaming, Node slave who doesn't instantly die in a 1v1 & a low T support (merp) using CDs to mitigate the other teams wincondition/burst go's
