Make Talismans purchasable

[Ancient Mariner]

As the title says, what about letting us buy talismans with ironite/gold/troopers points?
This came in my mind since i'm trying to get some talismans like Iron/Health and others to build up some characters, which seem not to be dropping like they used to before the update.
It's already quite annoying to have to farm the first worlds for a player like me who already completed all of them, but the problem is that in spite of the farming i'm only getting low level shards and runes, but not talismans
And i guess it's important for new players aswell to have some talismans to build up.

So having the chance to buy them (maybe with a limit per week so that it doesn't become too easy to make a set) would balance the low drop rate and give us something else to spend our resources on.

What you think?
