I’m playing a SSF classless character in 1.3. I can’t afford anything. I completed act2 at level 25 and have 80k iron. That’s about enough for DC blueprints. But then I can’t afford to buy items from vendors or craft anything or upgrade my stash.
First personal stash should be 10k, second 25k, and then 50k and more. And blueprints should be 10x cheaper.
That right there.
I have no experience with this, so I can’t relate to spendings (I assume you spend a lot shopping for items?). But I know for sure that the game isn’t balanced around classless.
To me the prices seem quite balanced. Even in my very first playthrough I didn’t struggle for iron bits (until I started crafting endgame components for the first time, but that’s beside the point).
So I’d say your struggle is entirely due to self imposed challenge
Hence I’d assume that this is an inevitable part of that challenge.
Embrace it, I guess.
P.S. Just my two cents, not the hill I’m willing to die on. I actually don’t care if stuff becomes 10x cheaper or 20x more expensive.
Why do you need more stash space? 
What did you find that you need to keep for later in a ssf? At level 25 I imagine you have almost nothing worth keeping that you can’t already equip/carry on your character.
Classless isn’t much different from a regular play through in terms of pace. At least on normal mode. The problem is that when you reach Respected with Devils Crossing, you have enough money for the blueprints, and nothing else. That means no items from vendors, and no stash tabs.
I played 1198 a couple days ago, and there the first stash tab cost 10k. The perfect amount. Your decision in act 1 is, do I buy an item or a stash tab? When the tab costs 50k, you can forget about it basically forever. Because after you buy DC blueprints, you’ll also need to buy Rover blueprints(another 100k). And then soon after that Homestead blueprints.
If you’re not SSF, most of the problems go away, because you don’t have to spend 500k on blueprints. And then you can afford your stash tab. So what’s happening here is that first time players get the sucky version of the game. I don’t think that’s cool.
Agree - for non SSF, it doesnt matter what it costs because you have an overabundance of iron. Then why not improve QoL encouraginf SSF 
maybe it’s an oversight/unintended consequence of moving the tabs around and adding the reagent tabs that personal tab prices changed from 1.2.1.6 to v1.3 ? - could poke Z about it/do a v1.3 ptr “bug” report if so
blueprint prices i don’t think need lowering, they’re already pretty cheap, if you lower them might as well just make them default craft if there is 0 reason to target buy initial desired ones and you immediately scoop up the full batches without a thought or care
