I think a storage space if deffinitely needed for keeping unique swords/armours (ingredients and crafting materials are fine I have never had a problem with being overburdened due to them since they all have weight of 0,01). However I don´t like the idea with unlimited separate horse inventory since you can call the horse whenever=> so it´s like giving unlimited inventory... I think the best solution would be an DLC quest for Vimme Vivaldi after completing which he will grant you access to your personal vault at his bank.
@ all people who say something like "simply don´t collect everything/ Geralt is a wanderer" ehm noone forces you to use vault if you would feel like it ruined your game experience
I guess yes since Vivaldi does not have branch offices in the rest of the world. If you want mastercrafted armour you have to visit one specific vendor, same with weapons, so why should be vault something different? It would be a special service after all (I suggest quest prequisite just like the ones with weapon/armor smith). On top of that it would keep the aspect of inventory management which you deserve so desperately (you don´t have access to all your items whenever you need them).And so everytime you need something you have to go back to Novigrad?
Yes it is and it is also the reason of this (and numbers of similar ones) topic- people want this to be changed and be able to keep all those nice unique pieces of masterwork... check poll results.You can't collect everything and you don't have to. This is the fact
" ... I lost a bunch of good stuff early in the game listening to these fools..."
Kaer Morhen or Vivaldi's Bank or at Inns like in the past games. Any of these would be logical and functional.
We need something to manage all this inventory.
