I think transfers would be immediately available. It's a new EU server, right? It's not meant to support new players (lol), it's meant to ease the strain on Teon, so it will be there for everyone who can't make it onto Teon to jump in as soon as they press the on button.
Otherwise, I think it will be on par with Teon/Franz/Bartz within 90 days, in terms of farming, botting, etc.
If they offered transfers from the beginning there is no way I would go to that server. You think shots are expensive now LOL, I can just imagine the prices of items there. It would be so top heavy with no economy. Would suck for the firsat 6 months until everyone got settled in. No way would I spend 50 bucks to ge there.
it all depends on how those transfers will be done as if say with you're full inventory and warehouse there won't be an issue at all and seeing it is a new server there isn't an economy yet to ruin so no reason not to do so.
