I have the exact same problem as you.. I am not playing since start, but long enough to have all the old, and in the past useable characters 7*, and on decent gear. I have 3,4 MGP, and now i am matched up twice with the same GP player, but he has far more G12 characters with 270+ speed Revan team which i cannot beat. You are clearly punishing old players with this matchmaking system, and non the less f2p players (as am i) are f-d. For me it was the first (not counting the bug start of this play mode), and the last time i joind in to this. Its just too frustrating..
