I simply can't admire and enjoy the lighter part of a MMORPG anymore. I always end up seeing then as a spreadsheet of numbers and tasks.
I do enjoy them, but on the pure gameplay, challenge-beating endeavour. The lore and the atmosphere are simply lost on the drive to play it efficiently.
Most new MMORPGs simply being a WoW clone don't help since I most of the time I am seeing a old game with a new skin, and I quickly start playing with my mind, not my heart.
This happens with other games too, but MMORPGs are specially guilty of this. But now and them there is a game which makes me care, or at least be intrigued, about the world, like Mass Effect or The Witcher.
