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.
Over time, the game changes.
2008-09 I played with Codemasters. 2010 I opted to move fully to Turbine US services.
2011 all those EU servers moved in with Turbine and I was able to retain some of those old bits.
Old stuff got converted to mithrils sometime 2012-13, I know my old cap 65s on Riddermark were swimming in the stuff.
I slowly merge the old EU ones to play Laurelin and Evernight.
I slowly make a mess of moving stuff to the US servers (can't decide where to play, leaning toward Landroval).
I'll just have to leave a few characters (perhaps half of them) more or less dormant on some extra server.
Main point is: don't delete.
Now server hardware space is set up in the Netherlands for the ex EU servers, making them properly EU once again. I feel an urge to at least go back to those characters and see what the game is like on 25ms connectivity rather than 125. Perhaps it's ace, perhaps it's meh.
Regardless, I'll be playing the US servers too but I'll retain the option to play EU.
Deleting is such a one way street to go down. I can admire the decision-making but we don't yet know if mithrils can be easily moved in the future, making those old characters useable again.
