In too many fights I end up with grid vision, so the DBM audio alerts help me not fail (trying to switch to bigwigs I failed at several easy fights, like casting during flame jets on Ignis). I scaled down the MT windows a bit since this SS was taken. I get small timers in the upper-right corner for boss CDs, which then enlarge and move to just above the MT window when they've got < 10 seconds left.

The action bars are a throwback to pre-dual spec, when I had everything on my bars. I keep weapons and other things I can switch in combat on my bars (shaman have to balance haste vs crit depending on whether they are CH heavy healing or RT+LHW, so being able to swap weapon+shield can add up to 70ish crit rating mid fight). I would do the same for my enhance weapons (screw digging them out of the bags after fishing), and all of my consumables for both specs. I've also started using my TotemTimer bar more and more, so I'm trying to get rid of the totems on my action bars as well (with the exception of a couple I have hotkeyed, like my castsequence macro for use-every-time totems and tremor totem). This is a big job for me, deciding what needs to be on my action bars and what I can handle with mods.

Also, bartender to my knowledge does not support character specific settings, so now, even though I have 4 or 5 bars I'm not using on my shaman, I need every single one of those bars for my druid.

I also am using a G15 keyboard, so I have 18 extra keys. Most of them aren't particularly easy to hit while you're on the move, but a few are in reach. If you look at the action bar button in the bottom left area, you'll see missing buttons and stuff in what appears to be strange places. That's mostly because of the order the keys are bound in, and what I can reach most conveniently. The action bar button for totemic call is in a really strange spot, but I can hit it easily with my pinky.
