Biggest reason most servers don't last long anymore is this chain reaction imo:
"/" represents OR
Step 1 - Admin f*** up/bug exploit/something blows up/hacked/GM @items for ppl/better server comes up/no competition
Step 2 - People are like wait.. I've only spend like a hundred hours playing this server.... Why the hell am I still playing here? There are like 2-3 copy servers with 95% of the same settings as these and admins there need some donation love too.
On iRO
Step 1 - People load their client; they already know s*** is f*** up, they know the game is imbalanced, they know they are playing the worse "private server" when it comes to $ via the cash shop but guess what?
Step 2 - THEY DON'T GIVE A s***. When you've invested (literally) you're WHOLE life into getting MvP cards (at like .02), god items, billions of zeny (without @autoloot), and all that, they aren't gonna quit. Many of them quit when renewal came because it made a game that was pretty damn imbalanced to begin with even stupider. The ones that stayed at the hardcore south park world of warcraft type of people except worse because it's 50 times easier to get gear and level in WoW.
By the way if I was playing iRO, once renewal hit I would've quit 10000%. Renewal f*** up so much s*** like extended classes. You see star gladiators? People spent 20 BILLION zeny on a 1/1/1 no autoloot server to get a DraculaAKPhreeoni book to leech people in thors and DG, guess what? You can't uncard ^_^_^_^_^_^_^; in other words, hope that gravity fixes star gladiators which they never will, and even if they do; it'll take a year or longer to get the patch from kRO that they are fixed.
