Shouldn't HQ hits give you more gp back?
I agree with this 100%.

What really needs to happen is give you full GP when you switch to a gathering class while in a main city. It's horrible to be doing something, the time for Darksteel ore comes along and you switch, only to be stuck waiting until three minutes before it goes away to have anywhere close to full GP.
It takes so long to get max GP. I come out of DF and switch to miner....stand there and wait. Even a GP regen on a long cooldown would be something.
