merge is a bad ideal, what if the population drops again? cross server is the only fix, at least u can do low level FPs, so hard to get a group going these days, i find most hte time i log on if it's not peak, u can't do anything!
i hope f2p brings more people back otherwise i'm going to quit!
btw, WOW gained 3 million subscribers by cross server instances/raids/battlegrounds, *hint* *hint* Bioware!
If the server pop drops it's bad either way.
I don' think you can back up that number about cross server grouping bringing in 3 mill.
I think merging is better, because then when you meet someone you like playing with you can, you know, play with them again!
