Just played through my first campaign, and this game is great. Very happy with it so far - but I do feel like the RTS combat is just a touch too fast. It reminds me of the spammy RTS days of Red Alert 2, which while still fun, seems at odds with the really deep upgrade system and dragon combat at work here.
I was able to just walk through NPCs using masses of units without worrying about unit abilities I had purchased. I found passive abilities were far more important, because while I could set aside time to use unit abilities, it was never necessary.
I really feel like increasing build/training time and inceasing unit health would do wonders here. I do understand that the RTS portion can't take 30+ minutes a round, or a campaign would never end. Still, maybe decreasing map population cap as well could help, ensuring there are fewer but more useful units on the field.
Adding to the problem was the fact that the only crashes I experienced occurred when I piled in a massive army into one territory (many times some of my units would spawn outside the map or underground as a result). If I was not required to mass spam units this could be avoided.
Anyways just my couple of thoughts, still in love with this.
