Props to blizzard: Gurubashi Arena is pretty fun now
I don't know if you've gone back an tried it since the patch, but I recommend you do. The difficulty is on par with previous single player content.
Actually getting synergy cards for your shrine makes it pretty fun. This is a huge huge improvement. Sure sometimes the opponent bull shit kills you on turn two. But you get to bull shit them back now, which helps.
I highly recommend that you give it another try if you didn't like it on release. And seriously blizzard, props for admitting mistakes and fixing them.

Something we debate here is whether we should track progress for things that don't have a reward at the end. The Rumble Run is a really great test case - defeating it with 27 shrines is a HERCULEAN task, that's a level of dedication far beyond defeating the Dungeon Run with nine classes. We didn't attach a reward to it. If we tracked which shrines you completed it with, would you expect a reward once you collected them all? How would it feel if you did it and nothing happened?
Based on feedback from Rumble Run it feels like it's better to track this kind of thing for the people who care. But I'd love to hear what everyone thinks!
