A consern about space efficieny since stormblood is not getting enough space increase

I think you overestimate how many that play WoW will find it "easy" to obtain the 40k gold needed per maxed out guild bank.

I played WoW for years and play it now. You don't need to level 46 characters to 110. Heck you don't even need to level ONE character to 110. I have a single character who is so far level 100 (I don't even have Legion yet), who earned enough money to unlock 6 bank tabs (cost 9,350 gold total) by the time she was level 80 (leveled tailoring some and just sold bags, plus leveled herbalism and sold plants). That was after returning to WoW following a multi-year break and starting completely fresh on a new server. Before that lengthy break, on my old server I had two characters for guild bank storage, and each of those guild banks had 5 tabs (the max you could have at the time), which cost very little (4,350 gold). It doesn't take very much effort to start a bank alt guild and store your mats, and the extra tabs that involve guild achievements are honestly just icing on the cake (the six tabs you can have prior are WAY more than what you'd get in FFXIV's slow-ass FC bank). Heck as I said, there's a freaking crafting mat storage in your normal bank now, too! That is on top of the storage you can already have in your personal bank. Plus you don't have to store armor for transmog. Plus you don't have to rent inventory space.

Side point: I know I'm not a hoarder, and I deny any accusations otherwise. I have ZERO inventory issues in any other MMO. This is the only one that causes problems, for reasons that have been very clearly outlined in this thread.
