Guild Wars 2

Of course, you can switch characters while in queue, but you lose the queue.

What I would like to see is queuing up with character A for WvW, then being able to switch to alt character B while staying in the queue with char A. When the queue pops, you get the usual interface and when you decide to go to WvW, char A is loaded in.

I like your idea or when you get into WvW you should be able to switch characters without losing your spot in that borderland. For example when your in a borderland and switch character, that character gets a pop-up menu giving you a few seconds to enter that same borderland.
