For those of you that are crafters, you will hopefully see the merit in my argument.
Those of you that want to play solo, you may not, but I hope you support my argument.
Due to the Size of the Bag we are being forced into specialising into Crafting roles, I think it is entirely possible for a Solo player to do the main armouring, weapon creation crafts (Blacksmith, Clothier, Woodworker) to support their own basic needs level by level.
However it is not possible to add in any of the other crafts (Enchantment, Food, Potions) as these are space prohibitive, due to the sheer number of ingredients.
This means that the majority of the community will be dependant on the small dedicated crafters for these products, which results in a thriving market.
We should all welcome this and should encourage Zenimax to keep the bag sizes as they are.
