i do believe that there are too many servers but from haypi's business point of view you can see why they are opening so many new servers. they are just trying to meet the demand of new players and task 35 players and the amount of level 10+ players in the first 20 servers is quite a lot of new accounts.
i think that they sent the requirements for task 35 too low and should have made getting a new account more of a reward by having to become a very high level in order to achieve it. this would motivate players to stay active to reach the higher levels in order to get a new account.
the only reason i have multiple accounts is so i can talk to friends i made through pvp. if i couldnt talk to the awesome people o have met through this game i would probably be innactive because the servers i am in (apart from s27) are so innactive resulting in me not having to spend time attacking people since there arent anyone to attack.
i think the introduction of alliance war would benifit the old servers massively as it will serve as an incentive for the top players to come back to have an epic battle with their nearest rival to get bragging rights.
i may have other points but i cant remember them as i lost my train of thought

EDIT: i also think that the rashness of the appointment of experts is bad because its throwing them in the deep end and they are drowning in the chaos. if they made them experts in the older servers until they got the hang of things, then changed their title to the newer servers i think that they would do a much better job of keeping the server under control and helping out anyone who needs it.
