A player leveling a gathering class has to pull up 2-4 times the materials needed by a DoH class to level through each 5 level range. This means that alone, if players level DoH and DoL classes 1-to-1, there will already be a huge surplus in materials until you're at the cap. This isn't even counting the fact that a good percentage of the gatherers are RMT running bots 24/7 and surplussing the market even more.

What this means is that DoH will quickly become a level and done thing. There will be almost no market for lower level ore or logs for DoL classes to farm as a source of income like DoH's at level 50 can go back and mass produce HQ lower level items.


tl;dr: Do something to improve the prospects of future gathers by reducing the huge surplus in materials mined compared to those used by a single player leveling both 1 gathering class and one crafting class
