Im not to this point yet but I can see getting there so this is a preemptive/theoretical/academic question...

My current main is an undead Prot Warrior in a T6 raiding guild and between all of my abilities and the macros I have for stance dancing, targeting, in & out of combat abilities, and general tom-foolery Ive used nearly all of the keys on my G15 and approx 20 macros. Where in the hell do you keep all of the macros to make multiple toons work? If I have 18 for the account and then 18 per toon that only leaves me with a maximum of 36 total macros, but probably its more realistic to guess at 24 per character on a given account. That just doesn't seem like enough.

Should I start saving pennies for an X-Keys set up or do I just need to learn to write more multi-function macros?
