Here is my UI. i don't recommend setting yours up the same way, because I feel it is a little cluttered and i need to clean it up. Hopefully there are some elements that other beastlords find useful. I welcome any comments, as I believe there have been changes to how burn buffs stack and I might need to make some tweaks. (Like crit damage % no longer stacks?)
Here are my basic driving instructions when using this set up
1. Click 6 to /assist the MA in raids or in groups
2. Click 4 to send in pet, and to make sure you merc is not happily sitting in Passive mode for whatever reason
3. Click 3 to do various combat strikes
4. Click 5 to cast spell. You can either multibind 5 key to your spell bar, or multibind 5 or 6 slots of your hotkey bar, if you like the flexibility of changing spell cast sequence on the fly
From here continue mashing 3/5, 3/5, 3/5 and you will fire off spells and combat abilities like a roman candle
You'll note that I don't call out Feral Swipe, kick, Bite of the asp, or other combat abilities that used to suck up lines in macro windows. Many of these abilities are merged with other combat abilities that can be Autoactived. For example:
1. Round Kick triggers Feral Swipe
2. Eagle Strike triggers Bite of the Asp
3. Tiger Claw triggers Raven's Claw
For burn, I use 2 hotkeys. You can see that i like to include buttons for each ability called out in the burn key, just to confirm my burn fires properly. Sometimes things don't fire and i have to go back and click the burn key again.
The first burn key is general personal buffage, so you can click when mob is inc, if you think it will be a short fight.
The second burn key needs to have a mob targeted.
After initial burn runs its course, i click Group Bestial, Ferociousness and Frenzy of Spirit. I realize Frenzy of Spirit is personally better than Dicho or Ruabri's, but in a group it's better to sacrifice a little to get those on the group instead
