I wouldn't get to over confident with L2 tower being better than Z-Ranger. The GM's are more than likely hitting one at a time before the new update. It is easier to constantly look for traces of one bot than all at the same time, i.e packet interference from different bots looks differently depending on what type of program is used. I am going to assume that withing the next 7-10 days your are going to start seeing L2 Divine and L2 Tower on the list of people getting banned before this next Big Update. Be Careful.
