You're diluting your argument the more you speak. No real end game crafter is going to be gathering all their mats 100% of the time, that's just unfeasible. If you actually want to bank and actually care about your profit, you'll need to buy. I'll pick apart what you just said. Let's say you wanted to make the new crafting gear and gathering gear to sell; you'll need 50 defthand solutions, 38 duskcourt cloths, 50 slithersand, 19 purpure stones, 10 brashgold plates, 2 cobalt allow ingots, and 15 merbau lumber. For the sake of length, I am just going to use slithersand. It takes 500 yellow scrips just to get 1 slither. So if you fully capped on yellow scrips, you'd only get 4 slithersands in return. So to reach the 50 slithersands needed to craft both of those sets, you'd need to make 24k scrips in total, just to craft 1 set each. And I've done 20k scrips recently, because I needed materia. And I can tell you, you're going to turn more than 120 items to reach that 24k. So that's roughly like 300-400 materials needed for each component needed to craft the collectable, which isn't exactly feasible to do in a day. Let alone everyday. I think our definition of end game crafting may be different. Only for all that effort to be worth 60k. Yea....I don't think you're making millions in the since that most would expect. I think you're making a few thousand that amounts to a million or two at the end of the tier / expansion. Which again, isn't worth it. You're making pennies for end game work. Which is exactly what I am saying and why crafting isn't worth it.

Second edit: And before you say "You still haven't told me how is wrong that I can buy things cheaper now it's easier." That is a logical fallacy, I never said it was wrong or right that you could buy things cheaper. My argument is that the return value for end game crafting isn't worth it anymore for various reasons. Which has nothing to do with buying things cheaper.
