I'm not sure this is better than your other.
All dragons are mostly the same, the difference being their colour and name.
Battle Golem, War Golem, same icon. They also look the same (model, even colour; skin).
Spell Breakers can't be trained. Check the techtree requirements again.
The map suffers from issues mentioned on your other one. Factions are not balanced. Chaos orcs are the strongest. However, they have the least units.
Building space isn't too much when you want to have more than 1 training facility of each type.
Elven Priests and Sorceresses don't have their third spell but those belonging to the humans can. Also, why not differentiate each faction. That would be neat. Try renegade wizards/hydromancers, something.
Maybe change the Dragonhawk to something else (model, name) to not be the same unit like for the elves or change the one for the elves with something else. Same with Spellbreakers.
There are two Human and Undead players with the same thing except the hero.
Maybe make a better techtree for the naga since they can build the fastest and reach the strongest unit in a matter of minutes. And the Royal Guard comes with all spells from the start.
But the Corrupted Night Elves are the worst. All units in one barracks and many of them have the same icon.
Corrupted Wisps can also harvest lumber.
The Corrupted Moon Well has no visible hotkey or at all.
Both Plague and Poison Treants have Entangling Roots. Kind of kills the weaker one's role and usefulness.
This would really work nicer in 24 players.
You're not really improving really. It's repeating what you did the first time.
