I'm guessing that you are not aware of the fact that there is at least 2 "plx increase the cap" posts every week.
They will increase the cap, as soon as possible, just like they have increased it in the past. It's not as simple as click a button and cap increased, if they increase the cap too fast they will mess up the server stability. Nobody likes playing with 30sec lag, let them take their time so we don't have to deal with that kind of lag.
Nobody likes the queue, but complaining about it is not really going to help. People that complain about it are also the people that don't care about supporting the server, because if they cared and donated, they wouldn't be sitting in queue.
Believe me, they are doing everything they can and will increase the cap when they can. Increasing the cap or opening another server requires money, feel free to help them gather it and donate.
There is also a way past the queue, which is with the queue-skip, here is how it works:
1. Donate money
2. Get coins for your donation
3. Spend at least 5 coins on a character on Lordaeron
4. Get 30 days queue-skip as a bonus for your purchase
