There is always a reason to oppose against it. And there is always reason to want it to happend.
Even if its wierd or not.
Yes indeed it will "Greatly" expand raiding oppertunitites for players all over the world. But is that it? Is this the reason they're doing it?
Server travel is already good enough and even "big" enough. There arent much latency problem(it is doable appearntly).
Before Party Cross-Over happend it was hard to gather party for Gordias Savage from your own server. When they made it possible it became reasonble since we meet eachother in DF anyways.
Then Server visit happend. Which "kinda" was a good thing(social aspect of it ofc). I was open for it but i didnt like it

i just stay on Spriggan.
