On one hand, I agree with you, on the other hand I can see why they didn't go with megaservers, in particular. Given the Company size limit of 100 and the amount of territories currently, it would start to feel a little crowded
That said I do hope they resolve the server issue for launch, they for sure have the resources to do so.
What I suspect is coming from something @Michael noticed last night where name selection is unique cross server. with that in mind I think they fully plan on merging servers at some point, which I guess isn't necessarily a bad thing overall (I personally don't really care what server I'm on at the end of the day, as long as I can play and not have to wait in a que aside from the obvious it needs to be in the same region). Seems a smarter approach would be to start with megaservers out the door to limit the amount of merges you need to do later on.
When we know an official server list for launch I will put up a poll for that and we can discuss more there when we start getting a better idea where streamers and what not are going.
