My opinion is that there are multiple issues with AL that should be dealt with using a complete overhaul of the system. Here are the big issues as I see them:
RNG – Too much RNG leading to lack of choice
$ - outrageous expense
Time – excess time to generate mats
Output – the output is either inadequate or undesirable
Buildup – Running the AL leaves excess 3* unfarmables with nowhere to convert them
One big problem was that the alkashard emblem output was nerfed by 75% in beta over the objections of the vast majority of beta players.
@MAGS661 's solution is excellent, but it only addresses the output problem, and the RNG issue for level 9 and 10.
Here is an example that illustrates the larger issues:
Level 1 of the AL has problems of RNG, $, time, and output. I have over 35,000 level 1 crafting mats. Let’s say I use 30,000 of those and run AL 1 1000 times. I will spend 31,000,000 food and get 1000 level 2 crafting mats and 2000 alkashards. The problem is that I have excess level 2 crafting mats, and even if I did need them I would likely need only one type. The output of mats is not very useful, and getting 20% of the way to a 4* mat after spending 6 weeks and all my food on this is ridiculous.
Here is a more radical solution.
Make levels 1-10 of the AL convert items to alkashards only. Items means anything including 3* and 4* unfarmable mats
Make the conversion costs and times much more reasonable so that one can really use it to get desired items. Enlist beta players and forum members to have input on what is reasonable.
Make the alkashards into a store, where you can “buy” everything from 1* items all the way to 4* ascension mats and emblems.
In order to limit PTW players, limit the number of 4* mats or emblems available in a month. After that, the store is out of those items but you can still get other items.
As an example, I would convert some of my orbs into alkashards which I would use to buy lumber which I need for events…or common herbs into leather strips, etc.
I know that RNG is the theme of E&P, but it doesn’t work well with the Alchemy Lab – choice is everything!
