I was at 5 star rank 6 with a 1 win streak going. The game I was playing was going to put me at rank 5. I had the patron warrior beat. Wiped his board, had iceblock up, and lethal next turn when, of course, the hover card delay thing happens. Somehow the other player can continue to play while I cannot. I tried rebooting eventually, but it was too late. Fucking frustrating. The loss stopped my potential win streak and knocked me back a star in rank 6.
I know blizzard just says "oh it's a connection issue", but I'm playing on my desktop with a stellar connection. The timing of it was pretty damn fishy as if the other guy was somehow able to trigger it on purpose.
But, assuming Bliz isn't completely full of shit, why haven't they improved on this. It has been around for over a year. They could try to auto-reconnect you or at a minimum alert you when they detect that you have dropped. I don't think they know how to fix it or it happens so rarely, that it's just easier for them to ignore.
It's just frustrating because I was considering trying to make an end of the month push. My highest rank previously was 4 and I was/am hoping to beat that. Would piss me off even more if it happened in Arena.
