Right now, Gathering is a bit too basic.

When I'm gathering materials for Cooking for example, I'm literally just waiting til I get 500 GP and then using the skill to get +2 items per gather.

It's similar on unspoiled nodes, just with a ton of waiting involved.

I honestly suggest SE make gathering skills more interesting, or make GP regenerate faster.
Perhaps even toss us some gear that increases GP regeneration.
Cordials aren't good enough, they aren't very available, have a long cooldown, and are only 300 GP. Most of the time, you can sell them on the market board for more than you'd gain from gathering.
