Just to make this clear though: I dont really care about the squish one way or another, I just don't like it when people pull seemingly random claims out of thin air. In these cases I prefer to inquire the reason for such claims and the source. Well that is actually not entirely true, I do care a little about the squish, but not enough to rage about it. The thing is I still doubt blizzard will pull the squish off in a way that it won't be needed again soon because of their terrible item 'philosphy' or that farming old content won't be impacted by it. The most curious thing about the napkin graph for example is that they wanted to squish iLvls for cata but already planned on going for an extreme growth over the expansion itself. I also doubt that they won't try to make raiding gear obsolete at the beginning of an expansion, hence there will be no linear increase like with already squished content, it will just keep going mostly exponential. If this is how they plan it, I'm not really sure they figured the core problem out yet, which is 4 difficulties, each with vastly diffrent ilvls and a couple of dated mechanics they might have to rethink.
I do browse the blue posts regulary btw, but I would never claim to have read every last one of them as most of them are not that interesting after all.
