Lets look at the most commonly posted problems people are experiencing:
"My guild was made on XXX Server and im level 24... I cant up and start again now.."
"I made this toon on XXX Server on Light population, it would take me ages to start again.."
this list would be too long so im going to stop there
FIX ->
Allow character transfers from any server that has regular queues over 10minutes, to a light populated server, that way the people who don't want to move are happy, and the people who wouldnt mind moving to a light populated server dont have any queues either?
Seems like an ideal solution which could resolve all of your issues within a 48 hour period. Just allow a grace period to move for 2 days
