jpgames.de Gamescom 2015 interview with Naoki Yoshida

[Cheraa]

In XI you already are using 231 for gear, 300 armory chest and 100 inventory, 400 inventory slots.

If this is still true, WoW inventory spaces are :
120 total bank spots
147 Inventory spots

267 total. That alone doesn't even equate to how many slots we use in the armory chest for all our job gear.

WoW has way more Slots aviable in WoD:

128 Inventory Slots
223 bank slots
98 Gathering Bank slots (Only for Materials)
80 Transmog Bank slots (only for Weapons and Armor)

Thats a total of 529 spaces. And that for every Character you play to 100.
