MH system is being tested and it will get improved as time passes by.Certain people are working on it and hopelly soon it will be even better.But it is nice news that server has less hackers than before.Before you could not play a single game without someone hacking.

or u can play dota2 wich is MH free.
i think ip ban can solve this problem
