I don't know if it's my Internet or something wrong with the game itself but it is irritating! In the middle of mobbing my skills will suddenly stop working... I can stone but I'm not going to kill 5+ mobs in BR just swinging my axe normally!
Then when it's really bad my skill animations will show but I can't do a thing except watch my HP go down until I fall. What's more is that the lag is so bad it won't even warp me back to town until after 5 minutes later... That's when the game decides to tell me that I failed to use my HP/SP stones. Really???!!!
