Describe the problem:
Don’t know if a problem. Reporting just in case.
So for a minute fight, 2 bugs ate more than 17% of the total legs piece durability.
I guess you can perform aoe farming in the culverts. In that case, the person who tanks will just probably get their armor devoured in a minute.
What was the expected behavior?:
Change the formula to make it less dependent on the amount of hits received and more on amount of damage received.
