"Movement speed will be reduced to walking speed."
Wow. I won't be using that much. Though I can understand stealthiness reducing movement speed it still seems a little harsh. I guess the idea is to pop the ability near a node when a mob is in the way, loot the node, get out and take the ability off.
Technically we should learn the ability for rank 60 and below mobs at rank 48, but the same could be said for Lay of the Land and other scan abilities. Gathering rank cap really should be 45 because content beyond that hasn't been added.
