I completely agree with giving rewards for solo. I played through the Alien Myths, Hades Betrayal, and normal campaigns on easy, medium and hard difficulty, and at the end of that (30+ hours), I had no xp to show for it, yes I got coins, but the amount is pitifully small compared to what you get from coop (an average of 1500 versus 3000). I get that it is a coop game, but punishing players that want to play the game solo (usually cause matchmaking takes a long time due to the small playerbase) does not seem fair.
