If you're being restricted often, something in your playstyle is probably causing it. I suggest you basically slow down. Do not join too many games over a short time span. Do not do things in a game that can cause a lot of screen lag such as casting certain spells over and over. Activities like these are what the servers monitor for as they are often used to try to exploit the game. We can't individually tailor the thresholds used by the servers on a per-user basis so as I said, try to change your playstyle in order to eliminate the restrictions.
Well hm, I've seen that FAQ before, but teleporting and throwing out hammers is not what I would call "causing a lot of screen lag such as casting certain spells over and over," especially since the bots can do it all day and not get booted in Baal games..
I'm just curious if one of the admins can look into my account and cd key and tell me what is causing the "lost connection to bnet..." message.
