Hired mercs have been a thing since as far back as I can remember in Mmos. I just figure "Poor Bastard needs to pay for the clear? Lucky for the mercs."

And then just move on.

All party's benefit from the accord. So long as people honor their word, there's nothing wrong about the practice. Sure though. I get the salt and it's laughable to me. But to assume everyone is using RMT money to buy runs is an exaggeration. I know plenty of wealthy crafters who don't care for content because they can easily afford such costly services, and to not be stuck in a learning "clear" group with people who are clearly still "learning."

All in all, it's just another way to make money. Guaranteed service like a player run casino. But that's... another topic for another day
