Questions about WvWvW and a little rant...
It’ll work itself out. As updates come the WvW caps will raise and the queue system will be optimized. Right now its a little low on the list of priorities because there are more pressing matters like bugs, trading post, quest issues, etc etc. In other words you’ll just have to wait.
And as far as I know you can only queue for one map at a time. But I can’t say for 100% certain.
Its not going to work it self out.. The devs need to make improvements for it to work out… They need to make improvements to the UI and server caps..
The dynamics of WvW battles are also in desperate need of revision. It’s next to impossible for some realms to end up on top within 24 hour period when some realms appear to never sleep. After the borderlands reset, it’s pretty even as far as points go throughout the entire night, then during the day while most people are at school or at work, you come home and find one server with 180k points with second highest at roughly 50k. It’s possible that these realms are inhabited by a greater number of Australian players as one example and will become a huge problem when server resets are farther between, due to the points for wvw perks system. If you find my post about actual WvW dynamics you’ll find greater issues for concern with the state of WvW in general. I agree wholeheartedly however with your point about not being able to see your place in the queue.
