Mentor roulette expectations always seemed a little ridiculous to me, as someone who doesn't queue it because I'm missing some levequests and just can't be bothered. Imagine being dumped into some extreme that you haven't done in like five years and just being expected to not only know how to do it yourself (a big ask; most people unsync older stuff as their "clear" of it) but to also be able to guide other people who might be utterly clueless about the game as a whole.

The only time I queued up for EX content was a Leviathan Extreme. Just the ARR one. This was back when getting knocked over the edge was permadeath. I queued in to help a friend, who'd done it in the queue synced and was sad that a dps had left and they couldn't fill the spot. I joined it "in progress" and wasted the next hour of my life because nobody in the group could follow basic instructions. Our first handful of wipes were in the first minute of the fight, when adds would spawn and our tank simply didn't pick them up. Told him repeatedly that he needed to grab the additional mobs (I didn't even use the term "adds" in case he was legit new new) and he just ignored me until it finally sank in. Then the gates around the perimeter went down, and even when I put a giant white circle over my head and jumped up and down while running to the safe spot (this was after 3 failed runs to this mechanic specifically; I did give them a chance to do it blind but I was tired and getting literally nothing out of this) they'd still just stand in place and get blasted off the edge. Finally the timer ran out and I got the hell out of there.

i can't imagine subjecting myself to this bullshit every day by queuing mentor roulette.
