I cleared a 76 about two months ago with an Unstable Sceptre Delsere's Wizard. Haven't played since then. I'm sure I'll be right back in the mix next season. I absolutely love this game until it progression slows down so much that I can go for a week without seeing an upgrade. At that point I tend to pack it in and wait for the next season.
Was happy to do all the season journey stuff to get the extra stash tab. Nice change of pace. I don't usually achievement hunt at all, but the stash tab was too good an offer to pass up. I didn't bother with the extra stuff for the wings though.
This season I ran two wizard characters:
Here's my grift pushing char:

Pushing grifts is probably my favourite part of the game. It's the culmination of all your farming efforts giving you the tools to then apply with a bit of skill and knowledge. Upgrading legendary gems is a great reward.
Here's my awesomely fun key farming char:

This is a variation of that build, designed to maximize Deaths Breath income. It was also pretty solid in grifts. I think I cleared a 55 or so with it without even switching out the Sage's set. In her left ring slot is the only item the two chars shared, the currently ubiquitous Bane of the Trapped. Other versions of this build use gold to buff armor but I found this to be faster and more reliable.
I love that next season some of the other leg gems are getting massive buffs. Should mean BoTT isn't an auto include for a lot of builds. Many gems that did additive damage are changing to multiplicative, as BoTT already was. Should be lots of fun!
I really enjoyed this season. Tweaking builds has never been so good. Had some good times swapping cubed items back and forth to try to fix problems when pushing. Great times. Got some good use out of
