If you're still using "stpc" in a party situation, you need to follow updates better. "stpt" and "stal" [iirc] were introduced recently and have the function of cutting down your stpc targets to just those players in your party or alliance, respectively.

I prefer using p0 - p5 macros on WHM, personally. I don't exactly have a massive need for any other macros, except maybe Repose. RDM is a whole different ball park though, I'd imagine.

If you need spells or low level gear see if it can be bought at an NPC shop because often times it is cheaper there.
Conversely, make sure you check the AH before buying stuff from an NPC. There's at least one case of some armour that you can save almost a massive 4 million gil by buying on the AH. That's an extreme example, sure, but it still pays to check.
