Before the new expansion my main harvester was maxed in harvesting and had gear and AA points to help with rares. Despite this I only found like 4 t8 rares in months of harvesting. I can't remember ever getting a second harvest. I finally gave up harvesting altogether.
I don't know whether it was a problem specific to the Test server or I am just the unluckiest harvester of all times. I couldn't even find rares on lower level nodes.
In the months I have been back I think I have found one t8 rare. As a result, when rebuilding my AA tree, I didn''t put any points into anything to do with harvesting.
A 1% chance of finding something is hardly worth the AAs you have to give away. Since I 'm not finding rares to begin with then my chances are nil.
I have no idea why a 1% chance would give all of you such great luck with harvesting. Depite this, I will give harvesting another chance and hope I am pleasantly surprised.
