For people using equipsets during battle or who have longer macros in general I have a couple tips:

<wait 1> can be used at the end of a line in place of /wait 1 on its own line, to fit more in one macro. So the quoted macro becomes:

/equipset 13 <wait 1>
/ja 'Charm' <t>
/echo 'Come to me <t>!
/equipset 3

Also, for using equpsets in battle, since changing gear breaks lock target you can add /lockon to your macro. For example:

/equipset 1
/ja "Unlimited Shot" <me> <wait 1>
/ws "Sidewinder" <t> <wait 1>
/equipset 2
/lockon

Hope this helps.
