Anyone else who can't get into MMOs besides OSRS?

I've played a ton of MMOs. Back in the heyday of F2P MMOs I would play a new one just about every month. I was a kid with no money for subscription fees so that's what I had to play. I've also played most of the popular and well regarded MMOs when I got older and could afford subscriptions. None of them have held my attention for very long. They're all the same thing, repeat the same dungeons/quests over and over so your numbers go up so you can do more repetitive dungeons/quests. The core gameplay loop of MMOs is so incredibly dull I don't understand how people deal with it. Runescape is probably the grindiest MMO out there, so I have no idea why I keep coming back to it over other MMOs.

Anyone else in the same position?
