Multi (2) boxing Paladins/Melee

Been viewing the forums for a while now, and have seen some great information that got me going on my other multibox ventures, but not quite the definite for this question...

Recently had an absolute craving to run 2 Paladins, and have seen a lot of talk on the forums about the "interact with target" idea, but having a slight issue getting it to function. I recently hotkeyed "Interact with Target" to J, and sure enough it does start npc conversations, as well as start an auto attack on mobs, but I would love some fine tuning macro info to get it to work more fluidly.

Anyone recommend/link me to - a basic macro setup to allow for my slave to function more appropriately in combat? Really just running into that issue of slave breaking follow as I start attacking from any distance with my master Paladin.. Usually causing the slave to stop short of the mob.

Has "Interact with Target" allowed for a more refined approach to "running thru the mob" with main?

Thanks in advance for your tolerance/patience.

i use a basic /follow focus macro after my dps macros

example
/assist focus
/cast Crusader strike
/follow focus

This keeping the slave with you pretty well? Been a pain trying to get him to stay engaged, even from the first hit. Is there a good "interact with target" for a macro yet?

its still a positioning game like it has been, but atleast i dont leave him if mob runs
Someone had a post about using mouse to click/move in their macro or something. Couldnt find it
