I know I have seen plenty of previous threads on this topic and I would like to join the consensus in saying that 4 tries to roll for a lvl 80 mod is ridiculous.
Thinking about the time investment to get to lvl 70 transmutation to only be stonewalled by this arbitrary constraint of 4 tries or a 25 percent reduction in durability is definitely disheartening and very frustrating. The quality phlog is a constraint in and of itself.
I think 10 percent reduction might be slightly more reasonable.
I am sure Citan is going to say it is in a "good place" as seems to be the usual response, but I hope they give some serious thought to all factors. I finally got a yellow lvl 80 sword after thousands of monster kills only now to have to wait god knows how long to get the mods I want.
Either reduce the durability loss or the 7 day wait period in between tries. We still need the phlog to change mods, which itself takes time to acquire.

Thanks for listening
