I can't put a number on how many times I've gotten 30+, 40+, even 50+ kills and lost a TDM match because of bad teammates or playing against a full party.
In fact, my highest kill game was a TDM match that we still lost
On the other hand, a loss in FFA where usually the highest skilled player wins is fair and perfectly acceptable for me. No relying on teammates, just yourself.
Many other high skilled players that I play with regularly share the same thoughts.
It would be nice to see FFA added to matchmaking. I know it already exists in custom matches so surely it must be a simple change to implement.
I think it would greatly increase the enjoy-ability of this game for people that prefer FFA.
