Let’s make Heroes 4 better.

and which one? If the fortress is on a swamp like in the third game, I'm all for it! The faction is good in many ways - and the buildings are good during sieges (for defense, and not just a little), the units are fast - the snake drakes and wyverns are worth mentioning, and especially if they also have good morale. The archers are good - they'll shoot before you can say "ouch." But the most important thing is the castle's music! And the campaign is easy in Erathia. Oops... I probably went off on a tangent. The main point is the first sentence - the rest is just rambling, I admit.
