Every Runescape version is grindy and looks awful. The only reason why people like it is because it's nostalgic, and because you can easily get addicted to it. It's just that, RSC is the stufftiest one out of all. Literally no one feels sad for it getting shut down.
Okay, maybe some people do. But just go play a private server if you like RSC, for whatever reason. There are plenty of private servers out there. And they don't charge you $11 per month just to play it.
