I'm sorry because I'm sure this topic has been covered ad nauseum.

If using a tank, 3 DPS, and a healer, do you use FTL or focus based macros?

With 3-boxing moonkins I used an FTL system. However, I also had pretty much every moonkin ability keybound and macro'd in some function. With my move to 5 boxing I'm not sure I have room for all the spells I used when concentrating purely on one class. So, I'm left with redesigning how I play and I'm questioning the FTL system.

I often use shift with my keybindings (for instance "a" is moonfire while "shift-a" is insect swarm). This was never a problem with 3-boxing FTL system because my modifiers to tell who current leader used ctrl, alt, and ctrl-alt. Will I need to stop using shift and reserve it for the FTL system?

Also, I turn with my mouse and use my keyboard for abilities (not a clicker). This was not natural for me a year ago (I used to turn with the keyboard and click many abilities), but after doing fairly high level arena and becoming tired of being called a clicker, I transformed to the "proper" way. However, with the multiboxing videos I've seen, it looks like many turn with their keyboard and likely don't have a hand on their mouse for the boss fights. Do many of you 5-boxers use primarily the keyboard for everything?
