DPS is the job of DPS.

the standard is that a roulette is random, so you can either get a speed run group or a slower paced one. That is the expatiation all players should have when it comes to roulette queues it is random.

This.

I just don't get why people "have to deal with it". What's the reasoning behind this "people should adapt to my standards but I won't adapt to theirs" statement? It's not a rethorical question, I want a legit answer. The expectation shouldn't be "the worst possible situation" but the possibility of facing both of them and adapt accordingly. As mentioned above, you have the right to kick the odd-ball or just leave if the group doesn't meet your standards. Or adapt. The later is the one that makes you a better player overall, in my opinion.
