Yeah, what we want with the Wilds is for there to be a risk component to getting those materials, which are needed for crafting high-end items. Basically by going into the Wilds you are choosing to participate in the economy, and we want there to be some competition there that goes beyond just who is online the most or who has the most time to grind.
That said, the “PvE” version of that would be basically buying the already-gathered materials from other players if you don’t want to PvP. Obviously there is going to be a premium built into the price based on that risk, but that’s what we want happening.
Finally, we will be introducing some additional crafting ingredients in future content that are gathered from high-end PvE as well. Not the same stuff (that would defeat the whole purpose), but for example you might need an ingredient from the Wilds and an ingredient from a high-end Shard Dungeon to make a new potion. Obviously not everyone would gather both themselves, a barter/trade would make sense for most players.
