100% agree and I experience the same in bronze tier as well! I recently got to Lvl 50 and tried out live arena for the first time. Actually I was looking forward to it, having a new challnge. But the match making just sucks from the start. I had only one match that was outstanding, presumably because there was a real player involved on the other end with similar ranked heroes.

The match making algorithm is the worst ever seen. I only have Lvl50 heroes (Legendaries, with some Awaken-Levels) and my "opponents" sport Lvl60 Legendaries fully awakened - and then always ban slot 1 even if my strongest hero is placed somewhere else - Or they ban Mikey, just because ;)

Not fun.
