With every patch, there are more and more sets introduced into the game. There are more furnishings added to the game. There are more style mats added to the game.
Some of these can be alleviated by subscribing to ESO + Some can't even be done by subscribing to manage the inventory.
I also know that any increase will cause some people to have the same issues when it comes to hoarding, but we are quickly, if not already there, reaching a point where even the non-hoarders are having difficulty keeping up with having enough inventory space to hold gear.
Please consider upgrading the amount of storage space that is available to players.
My personal suggestions
Bank: Upgradable to 400/800 slots
Storage Chests: Doubled in size (60->120, 30->60)
Guild Banks: Doubled to 1000 slots.
The limits for these have not changed since launch, where there was significantly less items in the game. It's only fair that the storage should change in tandem with the number of items available.
Another consideration (probably as another ESO + bonus, like the craft bag) is a furnishing bag that holds unlimited furnishings
Other options to alleviate some storage issues:
Allow treasure maps to stack
Allow surveys to go to the craft bag

EDIT: Addendum
Allow "NEW" siege to stack. Perhaps change it so that once you use a siege item it changes name to ____ (used) to keep the damage to the item unique, but any that haven't been used at all will stack together as ____ (new)?
While I wouldn't be against an increase in CHARACTER inventory spots, I'm of the personal opinion that those numbers are okay. Like, how can we carry 205 items, but our bank can only hold 240/480
