Only ones I really use are for targeting purposes...

/macroicon "Eye for an Eye"
/ac "Eye for an Eye" <t>
/ac "Eye for an Eye" <tt>

/macroicon "Virus"
/ac "Virus" <t>
/ac "Virus" <tt>

/macroicon "Energy Drain"
/ac "Energy Drain" <t>
/ac "Energy Drain" <tt>

Those are nice since I play both my SMN and SCH, so I never have to change my target to cast any of them.

/macroicon Embrace pet
/pac Embrace <mo>
/pac Embrace <t>
/pac Embrace <me>

I find having embrace as a MO macro helpful so I can have my pet heal whomever I tell her to without, again, changing my target.

Then I use the standard swiftcast res+summon macros so I won't repeat those.
