So I feel like there are a lot of things in runescape that the players would never let you change or remove but if they were never there in the first place and they were suggested that people would reject the idea.
The most obvious thing I can think of is the Multi-canon. Its well loved and 'should we remove it it?' would be a resounding 'no' yet if it were a new thing proposed today people would absolutely abore the idea.
What other things would players not want removed now but would be against if it were being added now?
