I don't see the point of feint macros anyway, I can already click my mouse faster than what it takes for my character to switch from one attack to another. When you feint too fast, the animations don't play properly and it's not very confusing for the enemy. Unless there's a trick to force the game to show the animations switching appear fast and spazzy, in which case there is a problem. And yes on occasion I've been feeling some people's characters can feint much faster than my character can do at maximum speed, which is weird.
