Well; It has been years since I contributed anything at all and I figure well; why not.
Basically there are a few nodes in the game where the node instantly re-spawns as soon as you gather it. While I have found a few I will only be posting one (see if you guys can find more!).
Shimmersand (6513, 6770) | Kingswood (rarely Mahogany).
Average 2 Kingswood per gather; 5sec cast time + lat; ~28-30 stacks an hour (@ 50 a stack)
Only tested on one shard so I would appreciate if others could check it out to see if they get the same results!
I believe I know why some nodes appear to do this but I am sure this will be fixed quickly anyway.
Anyways... enjoy.
