Not too sure if this applies to MHGU as I do not have it yet, but I keep experiencing people coming in, me readying up the quest, waiting for said people to affirm they are ready, for them to leave and I get stuck in a 30 minute wait time. It sucks ass, wanting to get good gear so you put up a multiplayer match to then get blue balled for a solid hour. If you're one of these kinda people, stop it, it's not fun for anyone, especially on a version of a game which is past it's golden age and has a low playerbase.

Feel free to share your stories in the comment section, I'd be interested to see if this is affecting multiple people or if it's just me.
