durability lost cap

[pepex]

i whant to suggest a cap on the durability lost when using the merchants repair, the cap should be around 85% lost of max durability.

the reason for this is to reduce a bit the high grade rare gap between those who use hammers and those who dont without reducing the use of hammers.

Well I had another idea about this.
Giving durability to hammer, so you could repair 3 items with 1 hammer or something like that. =X
