Ardus is generally seen as the worst hero in the game, so he surely needs some love.
I think that he is too hard to keep alive and still getting him to do something useful. He is too slow, too soft and lacks ranged abilities. He is an easy target for long and short charges as well as getting sniped by archers. His battlefield role usually becomes "Hide the points!" or "Expensive meatshield!"
