It is absolutely nothing like it, and if you can't see that then I'd have to think there is more to this comment than your feigned innocence, especially given your opening line of the first post.

There is a huge difference between a player pressing a button to have one character use warstomp, then another character getting the message on a second press, etc (it's no different in that respect than having warstomp mapped to 1 on one char, 2 on another, through to 5 and then pressing 1,2,3,4,5 in order) and pressing one button, having the addon decide for you which character is most in need of healing, what rank heal gives most mana efficiency for the amount needing to be healed and what heal to actually use. The first option (round robin) is one press, one action and well-defined by blizzard as legal...the second action is full automation by removing human decision making and interaction after the initial key-press and thus illeagal.

As to your comment that the software remembers which character has already used an ability and determines the next character, this is patently false. All the computer remembers is the order of the list of characters you entered and which index of the array it is up to. It has no idea what the ability it's triggering is, it has no awareness of the GCD, it has no awareness of different ranks of the ability to use and it has no awareness of if the next character has it's ability available or if the last character's use succeeded.

It is absolutely nothing like the automation we saw pre v2.0 macro and lua rewrite and for you to cast aspersion on the legality of KeyClone while pushing the fact you have a competing offering in your very first post just stinks to me....not of your concern about the round-robin legality, but of you trying to confuse and coerce people to use your script...for what reason, only you can say, and I'm guessing you won't.
