And btw I never said monks are bad, I even said from the beginning that they excel in pretty much any area: They excel in survivability, mobility, healing output, damage output and mana management. There is just one single area in which they suck and it is anti cc because they have zero anti cc and there is no other healer in the game that has zero anti cc, too. It just happens to be that anti cc is the most important area in pvp in mop due to damage and cc being out of control.
And as regard to my rating I normally don't post my ratings. I just wanted to "verify" that I know what I'm talking about and high rating happens to be the first thing wow players give credibility. Additionally me having high rating is not proving a point. In RBG I wouldn't have a lower rating if I played shaman. In 2on2 I play the (in my opinion) best comp there is, dk/monk. With every other class shaman is probably better in 2on2, just not with DK. And in 3on3 I play double heal DK because in any other comp than dual heal, monk is inferior to other healers (especially shamans) due to having no anti cc.
As i said I have no problem with agreeing to disagree on points that are up to opinion (like who's better in RBG). There just is no agreeing to disagree on facts, because they are either right or wrong.
Against casters it will be stronger because you have an instant silence, you don't have to wait for them to cast anything (in my opinion this improve against casters already outweighs it being less efficient versus melees, but you can see it otherwise, too).
But additionally - unless I read the tooltip wrong, didn't test it on the ptr - with 5.3 you can use it offensively, too, because it works on healers. You can silence a healer and thus get a completely new way of using the spell with 5.3 (which should give the ptr version the edge over the current one).
