GP Regen should really be a stat over max GP

It shouldn't regenerate faster than it does. A node spawns every twelve minutes. It takes 1 minute to restore 100 gp, 5gp every 3 seconds. It takes 6 minutes to restore back to full. The rotation for unspoiled nodes takes 600gp, 300gp for the 30% HQ increase, and another 300 for the extra hit. When they all hit, a chain #4, you use the skill that gives 100% Gather and HQ. I personally prefer the Gather +15% for 100gp and then the 300gp for 30% HQ. There is plenty of time in between the nodes spawn times for it to refill.
And if it could refill when we were in town and swapped to our class, I can level my battle classes, when the node spawns, port to town, swap to miner, port to node, mine, port to town, swap to botanist, port to node, harvest. There's already a surplus of rare node mats on the market. Do you want more, further decreasing the prices of said items?
