People still believe reason others get bored of a 2001 repetitive, boring and in many ways broken videogame is something that can be helped by changing a few stats here and there in ways that only affect the 10% of the server's population that even plays CS to begin with...
If you want to change something meaningful, I would suggest actually figuring out a way more guilds/players can participate in the event in some way. The current CS system only makes it so that if you don't play this game 8h a day, and happen to be a part of the 2-3 top guilds, you don't even get to experience the most fun event the game has to offer. I realize this is also true for other server, but given that you already changed quite a bit of stuff here to make the game feel more balanced and fun, I don't see why not.
Maybe add the option for the participating guilds to recruit individual players for help in the event, with a jewel/credits fee involved? The number of recruits could be increased by collecting signs of lord(for instance). I have no idea how hard this would be to implement, but it would be something to shake up the game.
