1. Craft at lvl 9 is impossible due to non existence of cards (or better said in more than 3 years only one dropped in cabal eu - fc no. 123 on Mercury). Even if by some crazy luck you get one, crafting anything is pretty much no go, since materials are close to non existent too.
2. Craft on lvl 8 is pretty much ridiculous due to mat requirements. PCK formula has insane amount of mats and craft sucess is LOW, same goes for glory pot lvl 3 or SEM, and i dont even want to bothertalking about crafting uch and fch (you need around 5 mil mats worth on mercury to get craft that is worth 500k at best). Either greatly reduce materials needed for craft or make possible to get more crafts per try. (I doubt that anything can be helped for SEM craft, thanks to Choas box extender that is main and huge source of SEM).
3. Where is formula card no. 60 (goodluck potion lvl 1)? I dont think it even exists in cabal eu.
4. make crafting results instant instead waiting 5-6 seconds for EACH craft. It might pass on prof. craft but at basic its absurd. To craft 5-6 stacks of amp or evasion pots you need 30 minutes, which is ridiculous.
For professional craft imo there is nothing that can really help to rectify situation at this point in game. There is one fundamental problem in cabal concept that lead to this point: THERE IS NO REAL ITEM SINK that can remove valuable items from game. After 3 years of game there is quite a big ammount of excellent items accumulated in game, and those are here to stay. On top of that drop rates of excellent items are way bigger than craft success. And intruduction of permanet perfect craft from weakened dungeons just made things worse. If you make craft results account binding it could help only a bit, but damage is already done.
There is a lot of other things there about entire crafting system, but this is the first that came on my mind atm.
