While I adore these duties, myself... a lot of my friends find these duties to be extremely frustrating. And one of the biggest frustrations is that, particularly for controller players, it can be difficult to tell what your spells/skills actually do when you're dumped in the middle of a combat duty with a bar of skills you've never seen before.

One idea I thought of that would be relatively low-impact would be, at the start of a combat duty that has you controlling a different character, have a brief text popup that says 'would you like to review your <character>'s abilities?' and if you say yes, a text display showing the icon and the tooltip pops up on the screen that you can spend some time reading to prepare yourself.

Also it'd be really nice if your NPCs were actually listed in your 'party list' for these solo combat duties. Especially if you're playing as a healer lol
