unit skills
There are some ways the game could take away some of its free form utility in order to give better choices to players. One thing that's been bothering me is the three slots for unit skills.
I'd like to suggest that these three skills be divided into 1 faction skill, 1 defensive skill and 1 offensive skill
or 1 faction skill, 1 defensive or offensive skill and 1 utility skill.
this way every faction could have acces to a unique list of skills as well as a basic pool of skills for everyone.
