- Maybe swap 5 with 6 on your druid so you're automatically healing the tank without thinking.
- Then have numpad 1,2,3,4,5 for an OHSH*T healz for each toon.
- Add a /stopmacro [channeling] at the beginning of mage and priest macros
- I would also have a separate key (say 5) where only pally attacks for building up or regaining lots of threat.
- you'll want to put innervate on some combination of keys for when you really need it, i use grid + clique for that. In fact, rebirth is also on one so you don't have to make 5 separate macros, you just click on the toon.
- Finally make arrow keys just move the slaves, this will REALLY help with fights like Forgemaster Garfrost, who is actually dead easy once you figure out the slave movements.
