For some events on Oqueue, I will click on the "wait list" button to join an event and it will instantly register, be highlighted in green, and the button will switch to "pending." Other times, however, I will click an event and nothing will happen. Or I will click an event and the action will not register for about a minute. While one event gives me problems, the others are still instant response. What's up with this?

There are time where the waitlist request won't make it to the premade leader, or it takes longer than normal. With WOD coming there has been what we expect is maintnance and upgrades being done to the battle.net server, resulting in delays and errors with battle.net whispers and friend requests. This effects the efficiency in which oQueue can operate. When b.net glitches, it causes issues and delays for oQueue communications.

There is also a situation where the leader of a group may be offline. It can take up to 3 minutes for a group to disapear once the leader has gone offline.

It can happen if the leader is tabbed out or has a bad connection too. Ive been known to tab out while leading groups causing all sorts of mayhem with my waitlist. People clicking it and nothing happening, automatically adding folks then deleting them etc.

Whenever I waitlst and it doesnt work I automatically blame the leader. :D

is it safe to assume that same goes to an invite button "lag", have to spam it sometimes to get someone in the group
