From your FAQ pre-launch:
QuoteThere will be loot from monsters in both open world and instances. It will be worth farming monsters, including in Open world.
* 3 Kromede runs: no stigma, a couple useless manastones
* Steel rake: 95% mobs are empty, those that aren't, just a HP pot or power shard
Maybe we have a different concept of the meaning of "worth". If this is going the same route as NA (just a lot more expensive), I'll use my Siel's month and out, waste of time.
