all of this is just speculation until SE makes official statement regarding this issue.

I just wished 2.0 came with way better space management. I'll use example from Mass Effect series, I remember ME1 being tad cumbersome with me having to manage spaces constantly. Fail to do this and player might miss some great loots.
Seems the developer takes this into consideration, and thus player don't have to worry about space management starting from ME2.

Elder Scroll series also has unique inventory system which allow players to fill their spaces with junks which impacts the weight than hinders their speed movement. Not really a bad system since @ least player won't miss important loots.

Current FF14 inventory system kinda reminds me of most dungeon crawler themed RPGs, tho the one game I can think close enough is Dragon Age Origin which has their own version of backpack and retainer. Not a really good inv management if I say so, tho luckily there are some unofficial mods that allow to have infinite space.

Not that I hate that system, it's just that this game makes spaces can really hinder my progress. Tho I suspect many might disagree with me. ;D
