I think everyone here agrees that more inventory space would not be needed if we had some form of equipment guide that we could cast glamours from. I would gain literally 175 inventory spaces from just that one change. I bought an extra retainer just so she could hold all my glamour items, and she's full of them. So much that I've had to start breaking them to fit in more.

In my opinion, I think SE spending money on more sever space for larger inventories (or more retainers - same thing) would just be kicking the can down the road, like someone said above. I'd much rather see the money that would go toward that instead go toward the development of an Equipment Guide that we can cast glamours from. That'll solve the problem for quite a long time as far as I'm concerned. If such a thing existed, I wouldn't even bother storing equipment for future classes, since I can just make fairly equivalent stuff whenever necessary and then Convert it when I'm done with it. I really keep all that equipment just for glamour.
