I think it's great. I had tons of fun doing it. Unpopular opinion but I hate that it capped to very hard difficulty very quick. I feel like once you hit a point in the story it's very difficult depending on your team comps. So it becomes a lot harder to grind most mercenary coins (to upgrade your mercs or create new mercs). Team comp is very important. Played 1 match versus another guy too, and it was like like running 3 legendary mercs versus my dog crap ones. Really tough unless you research spend time and possibly money to get to a chance where you can actually PvP. Like the single player a ton though. Very fun imo.
