I have had lots of tortol pots (unf) for months now and could not use them to lvl herblore because they are not usable as jangerberries are not in game.
I wouldn't mind having a way to get jangerberries & making them useful. Torstols are already used for making super combat potions but the "tortstol (unf)" potions have little to no use.
So I support this even though it's not really necessary. There's plenty of other ways to train herblore & getting 99 doesn't take awfully long.
