There are plenty of reasons why being passionate about your server can backfire. Admins that are passionate create the server in the image they feel their "ideal" server would be. The more passionate, the more rigid you become. It comes down to compromising your ideas or not having any players at all. Very rarely does a server get to do everything their own way while also maintaining high population. If you don't have a high enough population, you just lose money to keep your server. It's all for, let's be honest, a bunch of ungrateful players, myself included, that will leave when it suits them. The community is pretty spoiled. I've always thought the only good admins left are masochistic.
Running a server now a days is no where near as fun or rewarding as it used to be, that's why you just have vultures now that just try for nostalgia to make a quick buck with half assed servers. It's sad.
