On topic of Test servers, only if they do it WoW style and only have it up to test certain content just before released and not have it like Aion, where it is up 24/7. Most ppl moved to the test server to play Aion cuz leveling was so fast. Kinda killed most of the game. Personally I do not seen a need for it minus people being impatient or that test servers tend to jack up leveling so players can try testing content. And chances are ppl will only complain making stuff take longer to be released since most ppl here seem to cry about anything and everything. (which is beyond childish at this point)
