Eh not that i'm trying to be in support of the anti windower macro faction but smart macro design with the /macro set commands allows for timely gear swaps of up to 15 pieces of gear... however it still doesn't change the fact that you have to hit 3 macros which can lead to more human error and thus inefficient play style.

Given that you can accomplish 15 in 3 swap in rapid succession why should it matter if i swap 15 in 1? (though truthfully most cases its only practical to swap 12 which still would require 3 macros)
