Am I able to customize my UI?
Without a doubt! We understand the importance and benefits of having an active UI development community and support them as much as possible. Check out the UI Mods and Macros section on the official forums!
Are characters' names above their heads in WAR?
Yes, but you can control the display of names on your own client.
Will movement be "click to move" or "free", as it is in Dark Age of Camelot, WoW, and EQ?
Default movement is "free", meaning it uses the keyboard and mouse, and you can customize which keys/buttons do what. Any elements of click-to-move are in addition to the free movement, not instead of it. For example, your avatar will auto-face the target on ability use, not on targeting.
Is there be a /follow or a /stick function in WAR?
Yes, you can auto-follow a friendly player-character (a member of the same Realm as you) by selecting them and typing /follow.
