Hi!
I must say so far I'm pretty frustrated by this game so far as it feels very one sided. Other than my 5th replay of the tutorial and applying the errata where I managed a marginal Rebel win they have never even been close to winning ANY mission. The closest so far was "Under siege" where the rebels actually managed to do a fighting withdrawal and keep toe to toe for 6 rounds, but again after that it turned into a Imperial slaughter house with 1 withdrawn and 2 wounded heroes and the imperials scoring the last 2 needed tiles in turn 8. The latest is "Target of opportunity" where it seems impossible to actually achieve the goal. I managed to get the saboteurs out on turn 4 and on turn 5 they where in position by the archive door. But looking at the math even with optimal rolls the maximum they can do is 2 points each per turn damage to the door so they would need the rest of the game with perfect rolls every time to get through it (which would leave the actual core and the Royal guards to deal with), of course none of the rolls where optimal and in the end they didn't do a single point of damage. As for my heroes no one could even in theory do any damage whatsoever to that door. The only damage done to the door was from a frag grenade that could ignore the 5 defense, but that was too little to make any impact.
I'm supposed to introduce a friend to the game this week, but how will I sell it to him when it's absolutely impossible to get anywhere or succeed in any form? What worries me more about that as well is that he will only play 2 heroes and there's no balancing whatsoever in the game (like in Descent) to compensate for that, sure he gets some items extra, but he will be constantly flooded by enemies (if 4 heroes can't do it, what chance does 2 stand?).
