A few points about it.
A: is hotbars 10 and 9 vertically. they're never actually used i only ever set skills there so i can track cooldowns.
B: the 3 macro's i have here are all targetting macros. one is target circle. one is target attack1. and one is assist <t>. they're not used alot but can be helpful when everything is crammed in a really confined area. or to mark a key player in another alliance in 24 man content is if the main tank is in another party. makes it quicker and easier to target him and toss a heal if his own party is in bad shape.
C: is my pet commands which are changed when i cast the relevent summon spell. you can see my macros for these in the picture. also changes them on hotbar 10 again only for visual indication of cool downs.
set 4 is my expanderd bar which is mostly pet commands plus I have resurrection on there near swift cast and my summons as those are typically the 3 things I use swift cast for. so have the full toolkit on 2 hotbars plus the expanded one.
