I've been getting disconnected a lot no matter what character I'musing. I can AFK for the Tempest coins quest you hand in every 30 minutes, but being in a map with mobs, other players, or attacking disconnects me every few minutes. As does using a teleporter and moving across maps. -.-
If I get unlucky then MS stops working completely and I have to start up MS again from the website. This happens more often with that 2nd Job Skill though. I only use the Light skill for now, manage to last maybe a couple of minutes sometimes.
