(Subjective) The third story campaign map (Raven's Realm) is badly designed in my view.
I'd agree with you for much the same reasons. It's just not a very interesting strategic map.
That would make it 'gamey' and one of the strong points of the political system is that you make choices and reap the results of said choices... not take the choice best fit for your game-statistics.
While I respect that this was the designer's intent, the way faction support works undermines it. Because you always know what effect a decision will have on faction support, the decision is already "gamey" in that respect. I'd prefer to just have the consequences spelled out so I could make a choice of which I wanted.
I'm pretty sure that's the point here
Just because it isn't useful as a stand-alone defender doesn't mean it's not useful. I don't have a problem with units filling counter-intuitive roles so long as they're fun and interesting.
Also, Swen promised us AI Dragons while live on TwitchTV, pre-launch. We're still waiting
Would be cool, but I'm not holding my breath.
