When I quit rift months ago, the one thing that drove me there was the lack of an over-the-head nameplate option. Now that time has passed and addons have been worked-on, is there a V-bars addon/option available?
Not that I know of. But you can always check around the addon sites.
I actually don't use many addons in Rift but have tons of them in other games. Perhaps I simply got used to the Rift UI as every element can be modified by default. Even nameplates. Strange.
I'd love an addon like Aloft for RIFT, as it can be a bit of a nightmare targeting one mob among many. Even some better enemy bars would be nice, as currently they are tiny and I think unclickable, so a lot of rapid tab targeting is required sometimes.
