I have a level 100 turmoil zerker. Those stats are not overpowered. Your still using ultimate str lol. just get it 70 defence and piety then it will be pretty cool :)
You can bot the first in 1 month with a little bit of questing, sorry thats not worth $100/200m
Although if these are fully legit accounts i can understand why you feel it would be a fair price, sadly though, i dont think that many people are willing to pay that.
Good luck.
