Stash tabs are incorrect and feel like a scam when swapping between the two games.

As it is, we still have to use regular stash tabs (or at max a few of the "free slots" in other stash tabs, like the currency one) to store Breach crafting materials (Breach catalysts in PoE2, that are an Ultimatum thing in PoE1), Ritual has a stash tab in PoE2 despite already being a mechanic in Poe1 where it doesn't have a stash tab, and there's no way to store tokens for Trials of Chaos despite having purchased the Ultimatum stash tab, with the soul cores from Trials of Chaos being storable only in a separate stash tab that you have to purchase, tablets can't be stored anywhere other than the regular stash tabs despite there being a mini stash tab for scarabs in PoE1.

I purchased a Breach stash tab in Mercs and assumed, that it would be usable in PoE2, as both games have the Breach mechanic, however that is not the case

Scarabs essentially have their own mini-tab within the fragment stash tab...
Why can't people that have purchased this stash tab, and already have a map stash tab as well, use a tab for tablets as well? Even if one would be a mini-tab within the map stash tab, as an example.
Because unless you guys want to bring back scarabs (which can't really be a thing unless you get rid of towers completely and bring back PoE1 mapping), there should be a stash tab equivalent for tablets. And let me put emphasis on this... IF ONE PURCHASES A TAB IN POE1, AN EQUIVALENT TAB SHOULD BE AVAILABLE IN POE2. No BS like "you purchased a tab in PoE1 for this mechanic, however in PoE2 this mechanic is actually part of a completely different tab, so boo-hoo, you have to buy that tab as well".

Seeing as Chaos Trials already have the tokens, the tokens with rarity/specific entry costs AND rewards that are specific to it... Why can't the Ultimatum stash tab from PoE1 (which is used for catalysts and tokens) be used for Ultimatum tokens and soul cores? (and no, if in PoE1 Blight can have tainted oil be part of the Blight tab and not the mini-tab which contains tainted currency, then so can PoE2 have the same for Chaos Trials).

Why is it that there is a stash tab for Ritual in PoE2 but not in PoE1?
Why is it that despite buying all of the required stash tabs in PoE1, even stuff like the audience invites for ritual, are now in a completely separate stash tab in PoE2?
Why is it that I can't store Trials of Chaos tokens or soul cores anywhere other than regular stash tabs or the Socketables stash tab when it comes to the soul cores? When I have the Ultimatum stash tab, you know, the stash tab literally designed for Trials of Chaos tokens and rewards?
Why the hell are Socketables their own separate stash tab, instead of being a mini stash tab to the Currency one? When in PoE1, the currency stash tab has like 2 or 3 extra mini stash tabs?

As it is right now, the stash tabs are a scam.
Not only are they overpriced, but despite the games having mechanics that are the same, or take the place of the other mechanic, they simply don't have a stash tab for it OR force you to buy a different stash tab despite you previously paying for a stash tab, that contains said item slots.

In accordance with the tablet rework to make them even more into scarab-like items. We require a stash tab, that you'll already have in PoE2 if you have the stash tab with scarabs in PoE1, which will let you stash tablets, and perhaps separate them by type.

Either that, or the game should have a discount on first-time purchases of stash tabs for each mechanic. So that, let's say, a new or current player does not feel afraid to purchase a stash tab that actually won't ever exist in the other game, or said player doesn't get scammed when it's actually decided, that the mechanic actually won't have the same stash tab.

A half, third or even fourth of the cost of a mechanic's stash tab would go a long way for someone who (like myself) wants to have neatness in their stash, or a general ability to actually store items without falling over and crying themselves to sleep (just try going for divination cards in PoE1 without any stash tabs, or specifically the div card stash tab).

A stash tab costing full price in both games, when you decide to just randomly separate the mechanic into something else entirely making it two full price purchases, or not introduce the mechanic at all meaning that the purchase only affects one game without affecting anything in the second game, feels like an actual scam.

While a discount on the first purchase of a mechanic's stash tab would most likely, if not literally, boost the sales and make people more willing to buy mechanic stash tabs.
