Just a suggestion, I already think that Splash Damage is doing a great job with this game.
Kudos for making Missions refresh so much, and for having so many First wins of the game.
However, I feel as though leveling needs more rewards, and I think a free merc of choice every X levels would be cool. It does take a bit of time to grind, so I was thinking every ten levels. After level 20, probably wouldn’t be that helpful, so I don’t know, just an idea.
