First discussed here.
The offensive aura effect of a 2.0k item (Sol's) should not equal that of a 5.5k item (Daemonic).
The aura needs to build into Daemonic. Right now Daemonic is pretty much Sol's with additional attack speed. For any recipe that uses other recipes as components, all features need to build up. The single best feature of Daemonic was the -5 armor aura. Sure the armor for self and allies is great. Yes the attack speed is strong. But if you want +5 armor for allies you get RoT and it's upgrades. But the truth is Daemonic is primarily picked up when the team needs passive AOE damage amplification to heroes and towers.
I suggest Sol's giving +7 armor to self, with a +3/-3 Aura. Daemonic then gets updraded to +10 to self with a +/-5 Aura. Natural progression. This also is more in line with the buildup, considering that Sol's requires +10 armor worth of components.
