Between adding small crafting potions to vendor, adding potions to Towers (particularly god/satan), and now adding alchemy items to trees, it seems like they're trying to kill a nearly dead skill. Honestly at this point i'd rather they just do away with the skill entirely.
I'm sure tree drops will be just leaves, not all kind of alchemy ingredients. But... I'm with cantus, alchemy isn't worth anymore. I mean, you can still get profit with 65+ lvl potions or memories, but that's it.
