Crossworlds - Questions about skills

[Fatt_Shade]

I do get use of neatnes, but what i dont get why it strenghten only 1 unit ( out of like hundred diferent ) in all game !
Mechanic isnt only unit that have sumoning skills in game ( 15 at least have it ) so i think it unfair just for that, either neatnes buf up sumons of all sumoning units or not any of them. That is what i thought.
On neatnes usefullnes for mage i agree, but on +10,15,20 % for sumon droids repair droids i just think is stupid.
