EG Exploit : Lineage 2 Submissions

I dont know if someone not wrote that earlier beacose of much topics and messeges.In Egzecution Grounds is an Exploit/Bug.When U go through stairs up in EG and stand on the wall the monsters will not come to U.This is very good thng especially for mages and Archers.I dont know if this work on all servers.

Can i have a Premium Membership for this?
