Give us the ablity to transfer our progres between NA and EU. you could even monitize this by making it like 30 to buy a ticket that alows you to transfer your progress to either NA or EU depending on which one your on. i mainly want this coz im in the uk playing on na and i can no longer make it to the ingame things due to times 

Problem with this would be people would be abusing transfers to manipulate markets on regions as they are very much different. People could in this case make account stuff it with goods on EU where everything is min priced and pay transfer on NA and sell for max price example. Would be nice in general to be able totransfer acounts even from consoles and dead regions but issue always will be market manipulation, unless they would make system where any transfered items are not able to be sold or something similar, but this would require developers to spacifically make all items versions for just tranfer reasons so i doubt it would happen ever. I can highly reccomend you can try new side projest on EU on new account so you can still claim all your coupons on NA on that one or even make it your own mentee that is on EU and progress from there, Catching up nowdays is not that hard as it used to be

Abusing could be mostly prevented by limiting how often it can be used. So that abusing basically meas that you commit to it for at least a year or something like that. I certainly would not transfer my account for a year just to get a little boost.

I don't know if there is any region exclusive stuff, that could be a problem.

They'd have to sell off your storage and give you a silver value for it. Though that would probably open up more abuse for account sellers and stuff as well. Overall, probably just more issues from it for the small minority of players that would use it, than would be worth them creating systems to do it.

Combine the 2 realms.  Just make it so that NA and EU have access to each other's markets at a "tarrif", if the price is lower in another region 50% of the difference is payed in CM taxes.  After 3 months of this the prices will normalize then just make it so that you can freely use an NA character or EU character on each other's servers.
