Congratulations! There are a few of us in the Isboxer Discord that have been playing.

Svpernova is playing Barbs, he cleared GR80 as a 4 man last night.

I've been primarily playing WDs. I have cleared GR 99 solo, and am currently gearing them up the rest of my team to push higher GRs.
I'm also playing Wizards, and have cleared GR70 on 3 of my accounts, but again, missing some pieces.
Right now I'm focusing on gearing all the WDs to be able to 4 man push to get to GR100+ in a 4 man.

One other guy is playing his first season and is playing Wizard primarily and WD. I think he's cleared 100+ on his 4 man Wizard team.
