I used to game on a US server so I could play with my US pals, even though I live in the UK.
But dungeoning (even in a guild) sucks on this server because of the time difference of 8 hours. Even in an international guild, it’s hard to find 5. PuG is very frustrating and on weeknights in particular, even a 5-man PuG set-up is hard to come by. Especially for a specific fractals level.
A couple of ideas come to mind, both of which I would gladly pay real dollah/yen/pound/yuuro mubnies for (and I imagine others have suggested).
1) Allow me to have multiple characters on multiple servers. One on the US, one on an EU-based one. Simples!
2) Allow cross-region dungeoning, so I can join my US pals on their US server, even though I’ve moved my home server to the UK.
