And you don't even want to know the amount of players they made leave because of their mistakes/failures. They lost a solid amount of their playerbase due to banwaves occuring
1) with indo items that overflowed Jin/Ran (around 4000 items got removed mid-2013 - while it was reported one year before that - and yet with that removal there were still some that were made). I've seen a screenshot showing a glacial armor set on Jin (with conqueror levels shown) which had 80% hp. That set was recent as of January, and it was stolen by another player from Ceazar's defender.
2) with Rohanopoly abuse then its closure.
