It's because he's from goldrinn. Everyone from that server is so shit terrible they have to scale their gear up
Nope. Doesnt change the fact that there has been hackers on the armory before, reporting him will, possibly and hopefully, give blizz the attention to look at it. Within a minute they can probably see if its legit or not, if its legit, then np, they can go spend time to fix bugs, if is hack ,they'll ban him, i don't see the problem here.
It's a bug. He has only 3 4/4 items, which means he had enough VP before patch and got enough for more upgrades after patch.
