I've only played skirmish as I have no interest in the campaign,Ive played the old star wars miniatures game and various other war games including warmachine/hordes,warhammer and I also play x-wing.
From my experience with skirmish imperial assault, the imperial side always wins.I know darth Vader is currently the strongest followed by Royal guard champion so I've tried a few games without them but the rebels are still losing (note that I don't have twin shadows yet if that makes any difference).imperials can either stock up on stormtroopers meaning they can out number and eventually kill anything whereas rebels don't have this available to them (unless you buy multiple rebel trooper/rebel saboteurs packs),meanwhile if you try to out number the imperials they're strong enough to absorb the damage and still kill the rebels.
I really enjoy this game by the way,but this is a problem for me as I want to go introduce my wife to the game as its something she would enjoy too,but she would always use the rebels,we've had one game in the past and it came down to her ganging up on the stronger characters because lone models couldn't do enough damage on their own,but while she's doing that even the weaker imperials could pick them off one by one and it's kinda put her off the game.she will give the game 1 more chance but I'm concerned that pretty much the same thing will happen.
So I would like to ask you all,from your experiences with the skirmish part of the game,do you feel that the imperial side are too strong? If not then what are your reasons or any thoughts of how to solve this problem
