I have been playing many Real Time Strategies, and I noticed something that would really spice up this game.
The addition of a powerful unit for both chaos an order, a siege unit.
A hulking mechanical unit with massive damage, and area of effect. But slow an vulnerable to close range attackers (especially fast ones).
With a maxed out range but also a minimum range which gives it its weakness.
I even planned out what the opposing versions could be, chaos would be suited to a fire catapult, while humans always get a fire ballistae.
The siege unit would be located right before the giant, with a similar gold cost (around 1250), but a massive mana cost for the fire (500 mana or so)
If this addition was made, it would add many more possibilities for countering different armies. As well as add more use to currently almost useless units (such as the ninja, which is only solid for killing magi kills against a professional player).
