So don't pug. ¯\_(ツ)_/¯
Really not getting you... you expect some sort of amazing skill in a pug? Since when was that ever a thing in WoW?
I exclusively only pug M+ for weekly vault, if there is no guild group up. And my expectation of that pug is that they simply complete the run, not even time it - because for vault it does not matter. I certainly don't expect to join a group filled with guys pushing 20s that for some reason came to do that shitty 14/15 run.
