Heroes 6 - Discussion

I want there to be more hero skill slots in Heroes 6 (70% of all skills), like in Heroes 2, because in Heroes 5 there are so many useful skills, and due to the limited number of slots, I had to give up on some of them. In all the games, I always took Logistics, but in Heroes 5, I almost never took it because I needed to choose more essential skills like Defense, Luck, Enlightenment, etc. And I also want castles to provide more gold. I was especially annoyed by the small increase in gold in Heroes 2 and 4. In Heroes 2, a Titan cost 5000, and the castle only provided 1250. Try buying one without a mine; it's impossible. At least it should provide 1500, and the statue should provide 500.
