It seems that my priorities are wrong too so you are not alone. I am just not sure how these changes will benefit those that already dont care about their rotation and for me, as a summoner main, well it does take some time to get used to it but really its not that bad to play a summoner and if I missed redoing my dots on time or loosing my stacks because of somemistakes..well its no big deal for me since I still do my job quite decently. (The only thing that I want to change is Garudas skill contagion..>_<)
But I am somehow not surprised that inventory and glamour is so low on their list..I mean it was Yoshida himself that said that we just should throw the glamour away and not hoard it because we can just get it again..like its totally easy and fast to get it again >_>. (Even unsynch you really need good RNG to even see a certain item..lets not talk about all the instances with synch..)
I am just not really sure if they are so out of it because its their game and they play it so different that they dont have such problems or because they dont want to see it. (Or because working on changing the space problems would mean less retainer sells

)
Somehow they either just put out band aids (housing problem), ignore the problem completely or have it at such a low priority even though all players would profit from it in some way (Inventory/glamour)
