Any, any, even the smallest changes from x2 are imbalanced, x2 cause many official servers esp. after c6 had premium accounts. This server is x7, x7 carl, w/ premium and lots of item to donate and that part cannot be changed because this is the only possible product model that will bring enough profits. This server is focused for high level high end content fun, that's why if you go to clan forum part you see best interlude clans (90% of them are complete garbage but this is the best c6 has) dick measuring already b4 server even started. W/o these clans and people who wanna compete in this game this server would be impossible to open, but will all these clans play if they are the only players on the server? W/o any other players? 'Course they wouldn't. So you need to target as many let's call it customers as you can, and that will be not only good for profits, but also good for other players, and for that you need to sacrifice a lot, like exp / quest rates / retail newbie buff / BOOKS / 2nd prof. quest and it can't be the other way.
I personally would like x0.5-1 c6 completly retail, w/o cat top ng / low d weapon event, maybe even w/o shadow weapons, but this is not possible nowdays, too bad you can't figure it out on your own. And since this server is x7-x10 targeting lots of other players each w/ different preferences there possibly can be no x1 quests / books / etc. for your own fucking sake.
