Did you know about a cool trick for the Academy faction against a wall of fire? Take all your units, move them away from the wall, and then run with the Magnetic Golems to regenerate:smile11: :D! So, Fireball is better! And in general, the old Dwarf units are better than the new ones (except for the dragons).
You claim that the old Dwarf units are better... Well, well. Provide at least a couple of convincing arguments to make people believe you or at least understand why you think so. In my opinion, the Dwarf upgrades are more or less equivalent.
Bow down and hear our cry,
Our earthly rulers falter,
Our people drift and die,
The walls of gold entomb us,
The swords of scorn divide,
Take not thy thunder from us,
Take away our pride.
G.K. Chesterton: English Hymnal
