I'd like to add my voice to the discussion. I don't see a benefit to making the 24 and 28 slot bags soulbound. It doesn't make the game more fun to play. It makes me regret making the one 24 slot bag I've already made. It doesn't inspire me to upgrade my bags to 32-slot so they can be account bound... instead, it inspires me to just stick with the 20 slot bags I've already got, and resent the system.
