Solution for cross-region guesting
Doesn’t even need a doubling of storage space. It can probably be done with NO hardware changes at all. Just some database changes and some software adjustments.
Well, we don’t really know the details of what’s possible and what isnt. All I am saying is, if making cross-region guesting work requires some additional resources (and that’s what’s stopping them), then ANet should make it work and then charge gems for it.
Anet allowed free world transfers at will when the game opened and their servers didn’t melt. I took advantage of this to play with both EU and NA friends and never experienced lag in either region. It clearly is technically possible for them to allow people to play cross-region. If it costs them extra money to allow cross-region play then they should admit that and place a price on it. The claim that it is not feasible is provably false – they’ve already done it.
Wouldn’t it be simpler to have an international world with no WvW at all, for people of all regions to go there and play together?
