Robots everytime i farm shards

[Sheva]

There are nodes that do this. Specifically the ones I can remember are in Wellwick Wood in Eastern Thanalan.

While this is true, my suggestion would not just give you 1 extra shard per pull on one node out of a group of 4 at only a few spots around the world, but would apply to all nodes that have shards, crystals, and clusters.
My example would be at level 50 from any node that has shards you would get 5-7 per pull, crystals would be 2-4 and clusters would be still 1 per pull unless you used the an ability.
