why when i switch to a dol am i not at full gp its dumb

[Silverbane]

With the large requirement of items needed for HW crafts I can't find a reason why we can't do that for every 2 or 3 nodes

You can, with Cordials and Hi-Cordials. And Cordials are pretty cheap (800gp each at times) on the MB. During a heavy gathering session, I'll be drinking Cordials on cooldown. With that and good timing, you can hit the nodes at 9, 10, 11, and 12, bang bang bang bang.

It works like this:

With food, I can start the run at 650 GP.
Gathering for bulk requires 500 GP.
GP regens at 300 per Eorzean hour.
Cordials restore 300 GP, Hi-Cordials (available for blue scrip) restore 400 GP. Both have a 4 minute oooldown (which is 82 or so Eorzean minutes).

The last node is really tight tho. And if the third node is the 11PM Adamantite, I generally head off for DarkSteel (1AM) instead.
