[quote name='Chiyeon']They use Kalydo to load the game to the browser so users do not need to download and install the client in a PC which will take time. And since users can access it anywhere as long you can login to FB, a lot of users prefer NOVA server compared to the client base. However there is a catch. Since you need to load chuck of data on your browser, response time is not that accurate compared if you use the clients. So it is matter of preference.[/QUOTE]
Yes client have a better response time since important files are already stored in your PC, and unlike the Kalydo which sometimes experience latency (kalydo requires to reload a lot of game information from the server). The client servers have less players compared to the NOVA. I experienced it during low level days were in i cannot find any other players to party with. While in NOVA, you can notice the new characters strolling around.
