I've noticed how Wraxius tends to copy the enemies in the front line almost all of the time. As you may now, most heroes in the front line are physical. This makes Wraxius extremely useless, considering that his ultimate works best with magic heroes. He rarely copies the abilities of those in the middle and back line (where most magic heroes are found.) And if he does end up copying a hero in midd. or back line, it's almost always a physical hero. I've gone agains players with only one physical hero and the rest magic. Odds are he will copy the physical.
Please give Wraxius the ability to copy the heroes he benefits from the most (magic heroes).
