Question About Ironman Challenge Inventory Limitations

So I get that ironman players can't access the bank, but what happens when quest items start to fill their inventories? Especially when the crafting challenge is also in use, then a lot a player's inventory would be used up by crafting mats and tools.

Is this the purpose of the ironman challenge, to heavily limit the players' inventory space? Aren't there like 20 or so quest items that are used in later quests?

Maybe ironman players should be able to buy one-page in the bank for like 1 or 2 LE that other classes cannot put things into. This bank could even be separate from the regular bank.

But this post is more of a question than a suggestion.

 

Yeah, ideally you'd want to work around quest items - e.g. finishing the 6 ToL prereqs right before doing ToL.
