I'm confused by this. I've just started dual boxing and I'm using HotKeyNet and Jamba. And just been playing around with macros myself. I'm using a Warrior(master)/Priest(slave) combo.

Right now I use /assist Mastername before using any DPS spells. Then I use /target Mastername for my heals and buffs.

Is there a better way to go about doing this? Should I always be targeting my Master and just use focus to cast DPS spells? What about for healing spells?
