If relative power is unchanged

My opinion: The squish is irrelevant unless you're an idiot or simply hate big numbers.

Clarification: If relative power is unchanged, than the squish has effectively changed nothing. The item squish will, in such a case, be purely cosmetic. Numbers are not "out of control" in MoP because the absolute numbers mean nothing.

I will most certainly be testing every single raid I know I can do now after the item squish; in the event I find some I cannot solo, I will be very strenuously complaining about this fact on the forums, as well as providing numbers.

I will be paying particular attention to cases that are currently extremely doable, but very difficult... such as me and my wife 2-manning 25M Aurayia's achivement to kill her without killing any of her sanctum sentries; as case that are already difficult, those will be the most easily lost in the event they fail to properly implement the item squish (and yes, if they fail to preserve all relative powers exactly as they are with literally no change in relative values, I will consider it a failure, since I am not in any way inconvenienced by big numbers and I am not so stupid as to think that "TEH BIG NUMBARS IZ SCARY").
