I've had this idea for a while ever since I saw evoliths. In concept it's a very interesting idea that could've lead to a lot of interesting gear, however in execution it failed to prove to be a worthwhile commitment to obtain better weapons/gear.
From a personal experience I tried my best to enjoy the concept, it was a very painful experience having to deal with random evoliths from grad 1-8, only being able to do it once an hour, having to fight a certain NM that ranged from popped to time based. Then to makes matters worse we had to fight pixies for color pigments as well as obscenely annoying mobs just to make them more specialized in certain jobs. As well with the low drop rate on said items it became a pain when you actually had to fight against others who were trying to get the same item.
However what I have in mind is not related to the pain it took to obtain the pigments or the specialization for certain jobs but the evoliths themselves.
For something that took a while to obtain the one you need they could be easily disposed of/replaced through a simple synergy. With how troublesome it could be to obtain evoliths I believe evoliths should have developed more of a collectors system where you would do the following,
VS Evasion: Filled Triangle: Wind
Grade:Aquan:Birds:etc:etc:etc:etc
1:Got :Got :Got:Got:Got:Got
2:got
3:no
4:got
5:no
6:no
7:no
8:Got
Basically "Got" means they have obtained the evolith of that grade and have etched it into a evolith holder which is a specialized evoilth that compiles all the evoliths obtained onto 1 slab. Now just pretend the above grade 1's are all the mob types in the game. When a person has succesfuly etched every grade 1 into the evolith they are given the option for Vs All: Evasion + Grade 1. They would also be able to freely etch it into any armor of there choice or pull it off and place it ona new piece of gear if they wished without worry of losing the item.
So basically the idea is if you were to obtain every evolith grab from 1-8 for all mob types you would be able to etch an augment for Vs All: Evasion + Grade 8.
Compared to with how gear is now the evolith system was just never really given any love but I believe that if the developers looked at the system as a whole and see the potential with it, they can turn it into something people can have a lot of fun with.
The are more things I'd like to add like more ways to obtain certain evoliths, pigments and job specialized materials however if the developers do take note of this I believe the top priority would be to look at evoilths and see how they can turn it into an interesting system that people can enjoy.
