On a more serious note, based on my own experience using ArcHud and (presumably in your ui) Pitbull. Is ArcHud actually helping significantly? I used to run both but realised I was only ever looking the Pitbull frames instead. Not even remotely game breaking but worth thinking about
I use ArcHUD for combo points and energy level. Also for % hp on my target. So its mostly for melee dps. The icons below are from Droodfocus. The setup lets me view my 2 debuffs, 2 bleeds, my selfbuff and my Predator's Swiftness procs in one glance. it also shows Berserk, when up. When in bear, the icons change to the bear abilities (Lacerate stacks and Pulverize uptime).
I monitor around a dozen effects/abilities/scales in cat form, but at the same time, I need to stay behind my target to Shred. The ArcHUD/Droodfocus helps me to keep my eyes on the target to stay behind it. Then I also have my eyes where my procs show up.
I'd like to point out that I am suspicious of anyone that claims to be a friend of Best Buddy (I mean.... really?) or Tushy (there are only 2 things in her world: things you can eat and things you cannot).
