The unit growth rate is lacking, and quite significantly.

However, there is some good news for all Dark Elf fans in the demo: they increased the HP of Minotaurs (35 instead of 30), Chaos Hydras (125 instead of 100 + a new ability - the attack of the Hydra stack increases by 1 with each unit lost in the stack), and Black Dragons (240 instead of 200). In addition, Black Dragons and Blood Fury can now attack in the 1st round if you take the Fast and Furious ability, and Raiders will also be able to attack opposing units.
