I'm playing CIS on easy and I'm getting my ass handed to me by the republic, feels like my units are a lot weaker than they should be, for example I sent 16 destroyer droid to kil 4 squads of clones and 3 squads of wookies and they were wiped, and they don't even roll fast. This is generally the feeling I get from most units, they are very weak, in space the only thing I can do is spam lucrehulks as that's the only way I can counter the republic fighters, and in ground most the saber tank wipes the floor with most of my units.
The funny thing is that in skirmis I didn't get this and they worked pretty well.
