If anything, it is the crafting cooldown that should be reduced, and gathering stays the same. If there was no gathering cooldown, you could get 100 HQ ore in like 200-300 seconds, only thing slowing you would animation time and Action Points reloading.
If there was no gathering cooldown, an average gang could just camp at a mine, bring a brahmin, and in less than 10 minutes have over 400 HQ ore. That isn't how the game should be.
