Dave, please understand that "just for fun rounds" are no solution. People are already confused enough about the 2 existing modes (Ranked & Practice), and you can bet your socks on WGT not introducing a 3rd mode.
Besides, I for one may not wish to play a "just for fun round", but a regular Ranked round. For me and others who wish to play Ranked multi-player rounds, your solution brings no help.
Whereas if reputation tracking is implemented, this will serve everyone equally well both in Ranked mode and in Practice Mode.
danohi50: Here's a situation. I was going to set up a multiplayer round for me and my buds. I set it up wrong and the game started without my friends..now if i had to finish my round before i could re hook up with my friends...well now you know the rest of the story..
Exactly. "Forcing everyone to finish every time" is totally impracticable!
