Man, I am reminded high/G people like to go into low/high rank rooms just to overpower whatever monsters that room is doing. This annoys the hell out of me and worse is probably that most people I meet aren't bothered by this, so I just have to quit. Whatever makes you grind easier I guess.
I do know the one GAF room I joined back in 3U did this. I was bummed because I went crazy and farmed a bunch of bnahabra wings (which is a pain in the ass lol) for a LR weapon to help in a such a situation, but I didn't really get to show off because the guy I was helping was cool with people just bulldozing the monster with gear far above what's expected.
I have zero complaints about this.
I've alway been further ahead in the single players than the multiplayer, so I have (virtually) always experienced the monsters solo before venturing online. If a G3 wants to stop in, I'm happy to have the fight sped up. I've already gained the satisfaction from soloing the monster, so what's the downside?
Also, while coming up through high rank, I have played with a surprising number of useless G rank players. Like, shockingly bad.
As a bow user, my gameplay is mostly unaffected by the presence of other players anyway. I'm just doing my thing and they're doing their thing.
I am infinitely more annoyed by useless IG users who simply attempt and fail mounts over and over again and players who are under-armored and cart repeatedly.
