I don't understand this argument. You're saying you pentamelded to get HQ primarily, but we are telling you HQ mats are not really needed for high end crafting. To each his own I suppose, but I have never seen the benefits of melding for perception. Maybe when you're trying to get your Skysteel relics as those are entirely dependent on HQ mat turn in.
For example I am pentamelded for GP/gathering yield. Why, because I know that I don't need HQ to craft a 510 atheses or exarch piece of gear. SOO when they say HQ items for gathering is being removed....I personally don't care because I never really needed them. Now can I sell the overages that I gathered from a day of gathering absolutely. Is it going to make a difference in 6.0...not really. I'm still going to gather mats to craft, and that fact that I don't have to sell an item with 2 different price points is kind of nice.
At the end of the day it's NQ that I can turn a profit on time and time again. Why? Higher volume. I can farm 500 mithrite sand in about 30-45 min and make 200 per unit = 100,000 gil. That's 3,333 gil per minute.
If I was gunning for HQ mithrite sand, that would take hours (6 hours for 500) and knowing NOBODY needed it for dwarven nuggets to HQ them. But for the example... that's keep the same math. 500 HQ at maybe 400 gil per unit = 200,000 gil. 360min/200,000 = 555 gil per min.
3,333 - 555 = 2,778 gil is lost per min when farming HQ. Personally this makes me uneasy just thinking about all the time when gunning for HQ only, all the extra materia used and melded, the amount of gil used to pentameld astheses gathering gear.
I have made countless spread sheets on increasing my gil gain per hour and NQ win's nearly every single time. And it's all due to yield per min and time spent. Whatever get's you to the MB faster always makes the most money. I'm happy HQ gathered mats are going away, makes more room for other mats.
When 5.3 came out I made a killing on HQ mats, but it was short-lived. MAYBE a 48 hour period of selling HQ blue crabs at 10,000 gil a pop, but then people got there fully pentamelded ahestes crafting gear. Price dropped and NQ was being sold for 2,000 per crab.
