Balancing:
Regulus: quote "Armed with a powerful crossbow Regulus can snipe enemy troops and structures from great distances"
Sadly this is not the case.
Crossbow range to small either increasing range or adding a camoflauge which can be broken by demi gods and towers, this would fix the ever so weak hero even with the +7 range the distance is poor and almost on top of a rook still due to their size. This means Regulus can become enveloped quickly. If he is a support character then he should beable to fire from behind the front lines surely?.
The sniper shot could be more powerful with a longer cooldown (to compensate) as the maximum isn't powerfull enough, espeacialy when enemy Demigods have increased armour. Maybe with some damage over time too could also improve this, perhaps fire?
Laying mines: It would be nice to beable to place strings of mines by draging out a line from a start point, with the cooldown timer between each placement animation.
