Sadly, SE will nerf it eventually. IMO: The problem is not the difficulty, the thing is that these battles are still somewhat fun. Nerfing them means less fun for me. As a consequence, that's content that I will not being doing anymore.

A total unrelated, yet somewhat releated story. The other night, my static was queueing T5 with 7/8 people. We tried to get some random pug their first win. We did 5 runs. 4 out of 5 were their first win. It was fun.
