When gathering, if you hit the +1 attempt node and use a ward, you can then go to the other 3 nodes, complete the circuit and go through it again. When you did it twice you had enough GP to use Ward again, back when nodes hat 6 tic's. The new 4 tic nodes doesn't allow you to make the 3 shard pull on the increased Gathering node, every second round. I have around 330 back.

I'm going to guesstimate and say the GP recovery needs to be 30% more than what it is to keep up with the transition from 6 tic to 4 tic.
