It is an interesting idea, but I think it is not a feasible one during TWW.
Problem the first: the end state of KP continues to increase after a profession reaches its mathematical end point. Right now that would mean a player starting Engineering or Alchemy today would completely fill their wheels in six weeks. A month from now in five weeks, and about six weeks after that in a month. That would slowly apply to more and more professions for the next year of this expansion. While in some ways it seems like it would be nice, it would be a nightmare for practical implementation because Blizzard does not want players finishing their professions in one month.
Problem the second: Acuity is supposed to be tied to KP gains because of all the things that are purchased with it. 900 Acuity is for tools. 1000 Acuity for the books. Depending on profession there can be up to 2400 Acuity (might be more now with 11.1) for recipes. If people execute their KP gain to ‘catch up’ without the corresponding Acuity, the forums will explode with people rightfully claiming they cannot earn the Acuity to purchase the secondary and tertiary items for their professions.
Problem the third: How would you implement the increase? Adding additional Patron Orders would overwhelm the players you are trying to help. 50 Orders per day? The people who need it would say ‘nope, too many, not doing it.’ Add a multiplier to each KP item? Possible, but depending on the multiplier people who don’t want to spend the time and effort are still going to say ‘it’s not fast enough’ or ‘it’s not worth the cost’ and still not engage.
Because there is still an outlying question you do not address: What is the purpose of this?
Completing for the sake of completing is one thing, but it is not a good enough reason for such a major change. I am completing multiple crafters KP even though I do not have to because the points I am filling out now are irrelevant to my ability to use or apply the profession. Since completion for completions sake is optional, why should Blizzard accelerate KP accrual when the current ‘catch-up’ system is already in place and can reduce the time required to complete by 30-50% from day 1 crafters?
To ‘compete’ with first day crafters seems like it should be valid, but it shows a lack of understanding of the crafting system rather than being a meaningful argument. Any player can start a profession and on their first day make at least one item at max rank. Some professions even more. Can a day 1 player make more? yes. But not for long as with the current bonuses the new crafter is gaining more than a wheel per week. If they put a modicum of thought into planning their KP investment, they can be tied in production capability, not capacity but capability, in less than a month.
So casuals can make gold. I despise this argument because it shows even less understanding of the game and the crafting system. Not everyone can make gold through professions. If everyone was capable of making everything, no one would make money by crafting. The people who got there first would have whatever they made by being early, but the latecomers would actually make nothing because the market would be overwhelmed by crafters until the servers reached a functional 1:1 ratio of crafters to consumers. It is already happening to an extent, but accelerating it even more? ka-boom.
What end is your idea and recommendation trying to accomplish?
It is a nice idea that I sort of like, but I don’t see the need for it.
