Runescape got ruined because of Grand Exchange (Shops became useless; no need to look for stuff anymore), Bounty Hunter (Terrible and took the fun out of PK), and even trades (No more merchanting).
Lots of nonmems either quit or became mems because of all the update...there's barely any nonmem worlds that have over 500 people playing in it at any time.
I liked it better before trade limiting. Grand Exchange helped me advance my character but it took a lot of challenge out of the game, and made it pretty boring.
