the suggestion is that durability should have a reduction cap when using normal repair, 40% of max durability or something similar, i understand that this is done to encourage the use of hammers but not having a cap is like putting a huge sign saying buy hammers or dont even bother to make rares since they will end sooner or later with 1/1 durability
, after all the huge amount of crit spend to repair the rares plus the 60% reduction in durability are still good reasons to buy hammers.
