Yes, yes, yes, a thousand times, yes.
I'm all for something -- anything -- that'll encourage people to actually stay and finish 41 - 50. Earlier today, my party was held hostage because not one, but two (maybe more) people didn't want to do the last boss, because they "didn't want to run 1 - 40 again". We all had spent our vote kicks, so the quitter AFK'd and forced us to vote abandon.
My RL schedule is erratic at times, so fixed parties aren't much of a thing for me. Matchmaking was the only way I could finish my first run through the Palace. It's my go-to thing. It's a damn shame that I, and many other people, are being forced to abandon runs, because someone decided to go AFK.
