To my mind, it goes far more against the druidic ethos (for most druids) to buy from someone who cuts down trees (even in a forest friendly manner), than to teach oneself to craft using what nature provides the individual druid. It's just very difficult to understand why druids shouldn't be able to easily work with nature's bounty, to make a few tools for their use.
Especially given the relative paucity of spot/search enhancing gear in the game, it does seem a bit unfair that the mechanic is geared to the class, rangers, that don't actually mechanically need it. .
I'm not asking for foraging give the same amount of wood that cutting can give, and I realize that the the system is certainly preferable to one where druids can't harvest wood at all, but it gets very frustrating when every other class can gather every cnr without a possibility of not getting anything.
From what I have gathered from your last statement, there is a chance that you can forage and not find anything. Whereas, all other CNR is guaranteed at least one item. Is this a foraging issue or is it a 'unable to get at least one item' issue on a certain CNR?
