I often see people with beserkers (some have 3 of them) with only level 2 or 3 baracks, how is this possible? When I tried to buy them from the battle result window, there was a message saying I need to have a level 9 barack first.
I am pretty sure they are not hackers because it's quite a common unit for rivals on my radar. Anyone can answer this? It's a very decent unit with stat 11/7 or something.
