Pretty much the same feeling i got about blizzard store mounts and pets - Zero fucks given.
It's just cosmetic stuff afterall. Nothing to rage about, nothing to cry about, nothing to dream of.
The moment those transmog sets have current-content relevant stats of them I'll be mad though. I hate pay-2-win, and therefore I hate F2P model that abuses this "feature".
I don't see any point of being opposed to it.
I probably wouldn't buy any of it, but that's just because I like to design and earn my own transmog sets. If someone else wants to pay money for a pretty-looking set of gear, then so be it; it's not like they're buying it for a high prestige value, it just looks good.
