Hover text of important info is bad. Is this info so important?
If it's important enough to provide as hover text, then it's important enough that we want people to be able to see it.
Except your weirdos with your fancy-shmancy touch-screens. We don't care about you. Go away.
If the titles are confusing, it's the realm's own fault, and they will be the only ones to suffer from the confusion caused.
I don't care about realms. I care about players. And about the game overall. When players suffer, the game suffers.
