Is lag still a major issue with the game?

I get latency issues cos of where im from, but for me town lag has been reduced.

However, i get bugs and issues out the yazoo (is that the saying idek) eg: Opening the game im in a state of loading/this program has stopped responding for 5 minutes at least. The client can randomly close for no reason, and sometimes it fucks my entire desktop up to the point where i cant control my character, so i log out, and then cant type anything in skype or open any tabs in firefox and then only resolve i can find is to restart.

Its kinda like the whole sticky keys option turns on but its not that if you know what i mean.
