With the legacy system in full swing, I love taking advantage of the Heroic moment and legacy abilities. With 2 alts, and a main, that means I have 3 abilities that I can use during my heroic moment, but are essentially worthless on my hotbar during most of my adventuring and all times, when my companion isn't with me, (operations, FP's etc)
Also with the addition of the priority transports, companion dances, and other legacy abilities, there are now several new abilities that I don't have room on my hotbar for.
I would love to see a 'Legacy Hotbar' where I can put these abilities. If it can be set to invisible with a keybinding, or be shown when Heroic moment is active etc, that would be even better!
