1. Dwarves have 220 HP but can have high armor (cost: 400 gold). Their high armor seems to reduce more than 70% damage from physical attacks. Myrmidon's normal attack deals only 4~9 damage to them.
Templars can have 425 HP with full upgrade (cost: 550 gold) but have medium armor.
2. Dwarf attacks twice as fast as Templar. Dwarf soldier deals 27-33 damage per second with full upgrade (cost: 400 gold), while Templar deals 20-30 damage every 2 seconds.
3. By drinking Dwarfweiser, Dwarves can regenerate 20 hit points per second over 7 seconds, even in combat. The cost is 550 gold and its cooldown is just 10 seconds. It is better than chance-based Holy Grail. But there's a downside. They seem to drink it only when their health drops below 100 or so. However, if Dwarf Hall could benefit from Courage upgrade like the other soldiers do, that weakness goes away.

What if Dwarf Hall was a tier 4 barracks instead of Knights Templar...
