Which MMORPG could use a good reboot?

MMORPG reboots might be impractical and inadvisable, but games from Darkfall and DUST 514 to MapleStory and Linkrealms are all giving (or have given) it a go. But it seems to me that most of the games being rebooted during their lifetimes (or being granted a spin-off gameplay server of one form or another) seem to do so in an attempt to rescue themselves or cash in on a new playerbase — not necessarily to update themselves for a modern playerbase.

Some of my favorites unfortunately got sequels rather than reboots. I’d love to see Asheron’s Call get a solid reboot, for example, but I fear hopes for a player-modded AC1 to take us there are dwindling. Classic Guild Wars was a solid game too, and I’d argue that not nearly enough of it made its way into Guild Wars 2.

What do you think? Which MMORPG could use a good reboot — not a sequel or spin-off but a serious attempt to port the game into 2016?
