yes g15 software will allow you to macro a ton of things, i had once used it to make a macro to where i would press G1 and my priest would target a mob, cast 4 or 5 spells and kill it, loot it, and go on to the next, yes that was WRONG and i stopped doing it when i found out it was considered automation.
This was way before i was boxing though.

On a side note, it looks like Tim's post was deleted from that forum, i dont see it there anymore unless i just completely looked over it.

I dont know who that is but from that post he sounds like a real douche, we get enough heat, why would you throw another boxer under the bus like that? i dont get it.
