Guild Wars 2

I think that is good idea, like gw1, keep the team together if they win, increasing reward every match (ex.100 points more), after 10 wins they can face premade if the team is solo/duo.
the matchmaking must be updated to take this in account try to facing team with same number of winning streaks if possible, and asking member if they want to go on, replacing with randoms if some one need to left.

I’d get behind this, you can eventually filter into a group you like rather than rolling randoms each time and always having a 50/50 win excepting always premade players.

in gw1 i have found a lot a good player during winning streak, and some times we make a premade, or I invited them in gvg if someone of our official team is missing.
so when you have them in friends list you can go again with them making a premade.

Support this idea

I support this.

I do question how this would effect queue times tho.

Funny enough i had something like what the OP proposed i played 5 matches in a row with the same thief showing up on my team all 5 matches carrying the other 3 pugs we got every single game it was very enjoyable even though in a few matches the score was close too 500-150
