I got a decent one available yeah, I'm not even running Seraphim yet cause I'm still working on having a solid uptime of SotR on every boss and having as minimal waste of HoPo as possible. It's coming along nicely and I'm not flopping over on bosses anymore except a stray death on Kromog, but even that stuff is something I'm still working heavily on. My weakaura is definitely helping me along though. Just this whole muscle memory is still a distant stranger in terms of my rotation. Guess it'll come once I can lay off focus in terms of the encounter, where the encounters tactic becomes muscle memory.
My UI setup for reference: http://i.imgur.com/DfKBmET.jpg - The big SS icon alternates with SotR whenever I'm on 5 HoPo or during HA whenever I just have 3 HoPo. Also got timers popping up on each side in decent sized icons for DP and GOAK / AD.
