Good riddance lol. It was just riddled with bots and skilling in that game is pure cancer
For example, let's say you want to level up
Woodcutting. You click a tree and get some logs. But in RSC you have to click a tree, and wait for a chat message to pop up. It's either "You slip and fail to hit the tree" or "You get some wood". It sounds simple, but when you actually play the game, you'll fail most of the time.
The combat is awful, too. Almost all monsters are agressive, no matter how overleveled you are, or how much armor you're carrying. They'll always attack you.
There's much more to it, but
this video explains it well
