1) I liked that the balance of power remains normal throughout the game.
2) This is probably the first map where the limit of 8 heroes on the map seemed very small, but that's a good thing!
3) I carried the Grail with me throughout the game, thinking that I could place it in one of the elemental castles (or rather, the one in the middle of the fiery lake) and get all the spells - but I was wrong.
4) I got the Azure Dragons quite late, but I still managed to defeat someone with them... it was very difficult to give them up. I defeated the gate guarded by 1k of various strong troops without them; in that battle, I spent 1700 mana on resurrecting the fallen - just enough for everyone.
5) I played as Sir Mullich, and all the speed artifacts appeared quite quickly, i.e., +6 speed for all troops... well, it was just awesome =)
I decided not to upgrade Sandro, because he was clearly inferior to the main hero, but I still managed to gather 10k liches with his help.
6) The map is excellent. Thank you.
