Half of the minis I play are frustrating. Either it's clueless people (although you can't blame them if they are noobs) or, worse, leechers.
At least let us suffer a bit less by always being able to join minis with a friend or two, being in the same team. It shouldn't be very hard to make since it's how it used to be years ago.
EDIT (more rant): the only PvP I really enjoy nowadays is the PvP Event, and that's just one week, but at least I can team up with the people I want, and open-world PvP is always fun. If only the event lasted all the three weeks where there's no world boss... That would be a dream come true, so I could forget about lottery minigames.
