Umm... Slouken very specifically said AddOns, he did not give a general statement about multi-boxing at all in that quote, and I don't think it should be implied that he intended to say anything other than what he very specifically said. That is why I correctly stated, that he did not imply that multi-boxers cannot click. YOU are telling me what he "intended" to say, I am reading his quote verbatim. I am offended that you modified my post to comply with your incorrect interpretation of what he said.
While the use of the mouse to click on point A on screen 1 and point A on screen 2 is a little less questionable than the preceding example, it can still lead to some interesting and questionable uses of it.
Indeed, he did say "less questionable" and therefore it is IMPLIED, not explicitly stated, based on his post, that click replication is okay. I'm not the only one who read it as such -- the community MVP did as well. Therefore, it is IMPLIED by the thread, that it is okay. I really don't know where you're getting off editing my post here.
Let's take an example: take a solo boxer and let's pretend there's a 3rd party addon for solo-boxers that hooks into WoW and can send mouseclick events to x,y locations. The solo boxer would like to make a macro that casts Mass Dispell. The solo boxer sets up a portion of their UI on this 3rd party addon, with a little button for them to click on that sends a macro:
/cast Mass Dispell
MOUSECLICK X,Y
We're talking about 2 different things, I am talking about replicating a mouse click. A solo boxer is already clicking at X,Y. Someone using Repeater is ALSO clicking at X,Y. Repeater is simply taking that click, and repeating it in the other windows. What you are talking about is making a button that clicks at X,Y regardless of the current position of the mouse or whether it was indeed a click. I did not demonstrate, at any point, clicking on a UI mod that moves the mouse to a position other than the current position of the mouse.
