I have found finding rares from killing trenants and harvesting those mobs quite easy, usually a rare will be harvestable 1 in 50 or so trenants (Walking Trees).
On the macro side of life, yes /targetauto keyword will target any item that can be targetted with that keyword in it.
The thing is, it works like a sticky target, so in the case of targetting a "Node of Tin" using /targetauto tin will target the tin node.
The problem occurs when you run off to find the next node, hence what I call sticky node targetting, when you hit the hotkey with the macro again it will keep sticking to the last node you havested "Remains of Node of Tin" until it decays even if you run right upto a new node of tin.
I have devised a workaround which bases itself on trying to located any new node between your last harvested target and the next one you are looking for which has been working brilliantly for me.
The follow 5 commands in a text created macro I called "Find Tin"
/cleartarget (Clears target)
/autotarget tin (Node you are looking for, most like will retarget your last node)
/targetnextnode (Tries to find any new node between your last harvest and new node of tin you are looking for, if this node is tin anyway, bingo)
/autotarget tin (reattempts to target a new node of tin if in the vacinity if the next node command picked up a different node to move the sticky target from the old harvested node)
/autotarget nickel (Will move to the rare node for tin (Nickel Ore) first if sound in the vacinity. If there is no nickel this command will not change the new target of tin it has just located)
Hope this helps.
One thing to point out though, if a player by the name of Tinman runs into your area, the macro will continue to target the player Tinman until they move out of your harvestting area.
Also if you are going to use more than one word on the /autotarget command then you must use " " ..so ..... /autotarget "Node of Tin"
Take Care,
