they didn't do shit to fix op mosaic for 2 years, meanwhile banning people who play a bug build that some what give barb a chance against the top dog is ridiculous. not that I play it, just insane to expect any one to get ban for it. if its there and they didn't patch it, how can they blame player abuse it. its free dps, and barb are pretty rare these days vs warlock. most people didnt' make one this season.
You obviously aren't aware of nu-blizzard's stance on bug abuse. They expect you to know about it and not use it to have fun. That's what they do to people who jump on top of the houses in wow pvp battlegrounds and stuff. Even though they can still technically be killed. It's still an "exploit of game mechanics for advantages".
I don't agree they should ban, but this is obviously an exploit, not some super powerful build that they intentionally made like mosiac. My portal barb is so strong there's zero reason to play anything else.
