So this essentially comes down to "we won't do it because people will harass others".
let me tell you a story. Long ago, I was playing WoW. I was an elemental Tauren shaman. I had fun, and every time I went into the harder dungeons we cleared. Not mythic, not even raid, just endgame dungeons. We cleared and we had a good time.
Now, I ended up in a group who were doing consequtive runs. My only stake in the affair was coz I enjoyed it. Yet I got booted for the simple reason of not having high enough dps. So yes, there is weight to what Yoship says. Nobody knows if you use ACT, but if you go after somebody who does sufficient but not top dps and harass that somebody then you are doing something wrong and deserve the consequences. Use it for personal improvement and worry about yourself, not others, and you will be fine.
