SE has already stated that they plan on changing gathering. They gave the example that 'some lumber might only be harvestable by a BTN with 300+ STR'. Telling someone 'Hey over here there might be a tree you can chop, still doesn't promise they will 1. be successful 2. get any items of value 3. attempt to even harvest the tree. or that 4. the node will be 'active' and available.

The markings on the map don't say 'Hey you! Come Chop me down baby! I'm full of Pine-y Goodness'. You still have to have the knowledge of where to farm the good stuff/mats you need (or at least the brainpower to find a resource site where you can find this information).

Lastly, while I don't feel it completely negates the current gatherer abilities, SE might be planning on rewriting them/changing them as well down the road.
