I pretty much have the same hotbar set up of main attacks, cooldowns, and such. If I need a second hotbar I hold R1 and then pick the necessary hotbar from there. I've been playing as a Bard and ended up needing two sets, one for main attacks and one for songs.

I think I would do better tanking, mostly because it seems like it would be difficult to target/cycle through party members to heal. So, I suppose healing worries me more than tanking. I thought about trying out a few guild heists as both, just to get a feel for each one. Or maybe pull together some FC members who wouldn't mind me being a bit of a noob. I did also check out the macro deal, since my husband suggested that. He's been playing WoW for years. May look into that a bit more as well.

Thank you for your input!
