A "command chain," huh? Hmmmmm. Well, try the guides listed in the "Commands and Binds" section of the Guide to Guides at the top of this forum.
Level 50s:
BlackSpectre, Dark Defender (Guardian)
Thorin, Invul/Axe Tank (Justice)
Volcano Juice, Fire/Stone Tank
Professor ?, Mind/FF Controller
Stone Forge, Stone/Fire Tank
I've searched all over the forum and i haven't found anything in the way of basic macro guides.
I'm mainly trying to figure how to make a comand chain in a macro.
