As several people noted already, there are not enough macro slots to go around, especially if you play alot of classes.

I realize that there changes to the combat systems forthcoming, but presently, we need more slots, there should at least be a minimum of one row per class.

But to help with heavy macro users, I was wondering if it was possible to make macros execute an action number in addition to the action name.

i.e. /action "action 19" = executes the skill in slot 19, regardless of what it is without the need to type in the skill name.

Example of use:

Conjurers have alot of situational skills that don't merit a saved macro slot, like Paralyna, Silena, Poisona, etc. In combat, a Conjurer can quickly go passive, slot in the command by typing, and have it macro ready without going through the macro menu in the configuration setting. This way, we can use a macro slot for alot of skills quickly.
