The matchmaking is borked right now, there are only so many players a FT can play against.
When the game was still up the FT I normally ran with consisted of 26+ level classes (usually running 1 of each) against level 1 through 8s.
It is not their fault they had to verse us, I completely understand if they rage quit. It is not fun getting the snots kicked out of you through your rear end.
They should NOT be penalized for leaving to find a more balanced match that has a higher potential for being fun, it isn't fun for the high level people to just steam roll lower levels either.
Until the player base expands and matchmaking stops being a troll, there will be stacked matches and people will (understandibly) quit.
The true fun is when both teams are in equilibrium and it is a struggle for both teams to cap.
Heck, I'll uninstall the game if they implement a 30min lockout. Sometimes the guys I enjoy running with DC, or the game crashes on 3 out of 4 people, or it boots us from the fireteam. Why should anyone be penalized for a gameside "Whoopsies!" that no one has control over? Sometimes there are 4v0 matches because people quit in the loading screen. I don't mind, but do you really want to penalize 8 people for quitting a match that neither side wants to play? A 30 minute lockout would actually hinder the game on all accounts, matches would be found slower because everyone is locked out, people would complain on the forums while people say "quit whining and go find a fireteam."
Nobody can play because they're trying to find a decent match and people look like a certain male body part used for urinating for telling everyone seeking a decent match that they are a bunch of whiners. If there are no players, there is no flow for GRO.
If you need a real gun to feel like a real man, then you have a problem.
Playing with guns is no better, if someone is playing with a gun in my vicinity then they need to GTFO!
And honestly, if they're quitting right off the bat then you're better off. You at least have the oppurtunity to get some help from those open spots.
