The only problem for me is the login system kinda weird, first i play/created account through wifi and doesn't have problem but i cant login using mobile data (server unavailable after choosing char) , after few days my wifi seem slow and kinda switch to mobile data in game (reconnect) after that i cant login using wifi connection "server is unavailable" but i can log in using my mobile data connection, kinda stupid. it save your last ip addres? *both Internet connection work well
