What would keep you from continuing to play there?
Well they sit there now, because I play on a couple NA servers. Consolidating to 2 servers from the 9 that had toons on them.
Before you ask, most of the toons on the other servers belonged to my kids, but they since moved on to their own accounts or play other games.
Even when the kids were not playing I would login to all the servers once a week for the hobbit gifts (gold and silver) to benefit their toons.
I will most likely delete the toons I can not transfer to the 2 servers I am consolidating toons to.
It will waste hundreds of mithiril coins, hundreds of gold coins and so on, but it will keep me from being tempted to login on them thus saving me time.
