I have to say... I found this to be... difficult to play. I mean, I don't want to offend you, but the typos were too often to be "typos", they were just terrible spelling, and grammar.
And, you have it set so mobs just charge in your base every 10 seconds... in the second map that can be a real b*tch. The only way to survive is to hope you get at least three friggin' Rebels out of the war tent before the second group arrived, and with the time for each rebel set for about 18 seconds, that's a difficult thing to do. I also managed to get all heroes to level ten, each mission (Didn't make it past Mission 3, I'm not including interludes as missions.).. because the friggin' mobs are givin' a crapload of XP, or heroes earn XP too fast. Either way.
Should you decide to take the public's opinion, I'd like to set mine in:
I'd like to have a few less typos, I could hardly understand what you said!
I'd like to have unit construction time reduced, or mob arrival time lengthened.
Fix the Hero XP/Reduce XP mobs give out.
Your campaign is otherwise okay.
