1-The Skeletal Mages got 30000 health, and it takes ages to take them down even if all Mages unite against one.
2-The spells are so weak and don't deal enough damage.
3-You start with 1000/1000 mana as player 1, but with 1/1000 mana as other players and mana takes ages to regenerate.
4-All potions, items, units are expensive.
5-Gold is hardly to be acquired as you need to kill Skeletal Mages to obtain it and that'd be extremely boring.
6-After killing 4 mages you get to have enough gold, only to recruit one unit.
7-The most powerful unit you can hire can be easily beaten down in a few seconds by a single mage.
Allow me to rate this map 2/5, due to it's lack of new features, ideas, and due to it's extreme boring gameplay, should you need help with anything except models, then inform me and I'll be very glad to aid you.
