We have enough classes, enough people, enough possibilities of gear, to keep people interested. If people choose to rush it, then it's their choice to be bored and friendless at the end of the day. I definitely agree that this gambling theme is just a fabrication of content and just spoils your hard earned time and effort. End game is not gear, end game is content, and doing the content. It's also helping people reach your goals. Once that's reached, you got pvp and woe, OR, costumes. There is ALWAYS something to do, and RNG is not something I'd prefer to do. It doesn't make people want to stay, it makes people want to quit.
As mentioned before, what is lacking on this server is some sort of custom content, like those nightmare mode instances suggestion. We have nothing beyond official kro, which is nothing exciting. If people are bored, it's not because they're geared, it's because the game has nothing to offer to fully geared players, but to make a new class, which a lot of people don't want to do. RNG has nothing to do with people staying behind, and if you believe that, you're a nut head. Learn to enjoy your time, rather than burning it mindlessly over and over again. It's insanity after all.
