Current HP bonus on regular units levelup is very disappointing. It makes no incentive to levelup units and keep them alive. Please, add some more meaning to the levels system, as any other fantasy 4X does. Its okay to have it automated, w/out according dialog, but let them increase different stats and acquire some special abilities. Lvl15 squad SHOULD be different from lvl1, they are hardy veterans after all.
Maybe also chance to upgrade their weapons/armor from loot?
