At this point, the kick function is less about removing players legitimately harassing others in a party and more about someone's baseless, opinionated crap that is the result of said person's epicurean standards not being met. That, or some imagined slight that you apparently did. Its these kinds of dumpster fire sensibilities that are half the reason I really really do not like doing roulettes with randoms. One moment people are whining about the green DPS being a healer, the next its about the blue DPS not being a tank. Being new and not knowing how to do a mechanic after asking "what do I do?", or being blamed for someone stacking on you when 98% of the field was not occupied by you when you had no reason to move and thus were standing there attacking the target to begin with.

tl;dr, the kick function is little more than a catharsis.
