You might not want to face it, but there is a difference between controlling 5 characters and binding an off GCD ability to a GCD one.
Also, this whole idea of jealousy is hysterical! No, people are not jealous, people are pissed that cheaters are ruining their game. It screws up the nodes, it screws up the economy. No, there is no jealously, there is disdain for people who cheat and disrupt other people's game play.
Also, love how some come here and say "30 pages to say" and some generalization like they were right to begin with. The poll says the majority doesn't agree with this and there are threads about this on the official forums too and it's a problem. Are we really gonna be arrogant to the point of saying it's "jealously" and ignore the clear message being sent? Truly deplorable. This is always the same on mmo champ. People think that by repeating the same thing and still be posting 30 pages later through means of stubbornness that you were somehow right. No, you weren't.
MB IS cheating.
Blizz allows it.
60% of people here think it's cheating.
An amount of people large enough feels affected by this issue for these threads to pop up now with a lot of activity (cause it is rampant in game atm and it is often tied to botting).
These are the facts. Not strawmans of motivation or that anyone is asking for a purely equal game, when that is impossible in an mmorpg.
The thread is 30 pages long cause people are sending a message. I am very sorry that that message is not the one some (in particular the multiboxers themselves) might want to hear. But, it is clear.
