This issue should be corrected in today's patch. There is even a checksum verification to stop people from modifying the scr_base.
Yea i am well informed about this trick also and yeah its easy to check ..GM have to log on account or w/e and just check. Some of them are not that dumb to use leech as warrior ..They will just put on critical and some other things i can tell the names already who is using that from Tibet boys xD i meant ppl who grind in tibet beacuse i am well geared warrior and I can easy check who is on it but the point is that they used this on other servers and I had chance to play vs them xD and ofc they were banned there also after we found out what kind of bug is that i hope GM will do it and reset their masterys atleast in case they wont ban them xD )))
This is one of the let's call them "few" exploits which are in the game and so far there's no progress
