Potions in Potion Recipes in Reborn?

A quick question, there were rumours that reborn could require regular potions to be used in higher potion recipes? Is that still a thing or was that idea dropped?

I would not like to find that out on monday since the last raids and dungeon runs likely happen this weekend and we could sell and use our old potions for this if after that they are only of use for leveling.

If they are used for reborn recipes though I’d rather use the weekend to farm and stock up on them before the beta launches.
