So far hes undercut my gems by 100g I had inferno rubies for 190g he puts them for 80g and has large amounts. He cut down for volatile airs from 18g to 9g and volatile lifes to 2g. Not too mention cut someones mechano hogs and flying carpets by half as well.
How do you handle some prick like this? He is obviously a botter to not care about the ah economy like that.
