They handled it the same way FFXIV does. Doesn't allow any more instances to be created past X number of instances. Before cross-world parties, many lowbie instances hit cap and you had to run back and forth across the zone in until a party left to get their spot.

However their instance's are on separate servers than the world server, and possible groups several worlds together on the same instance servers. I am unsure if FFXIV's are ran on a separate server or their worlds server but since some worlds had hit instance capacity and others didn't, they probably just run on the same server as the world. Separating that would make more space and speed up instance connections probably but cost more money and they'd need to develop the coding to do that.
