GMs introducing imbalanced headgears/gears (+3 stat/atk+ & etcetc in one headgear) and spender's bonus. Antibot was introduced, people getting banned, complained about how "buggy" antibot is so antibot was removed and they were unbanned (lol). People have been selling BILLIONS of zeny since then and openly making post about it. Game crashing whole lot everytime new headgears were introduced. just stay out if you value your time/effort unless you want to brawl with bots and p2w players 24/7.
