1. The farm's pathing size should be bigger for this model. It looks weird when you build more one near another. Units might get through parts of it.
2. Archers can't attack buildings.
3. The techtree is very similar to the human one. Maybe you could find something else instead of improved lumber gathering and masonry.
4. The Marketplace=Arcane Vault. What about thinking of some other items?
5. The Ballista has no projectile.
6. The Paladin's spells aren't properly placed in the ability learn menu. The same after learning them.
7. Beacon of Hope shouldn't be an autocast spell if it's designed to be permanent and limited to 3 units.
8. Turn Undead heals non-undead units. It should work as Exorcism. If not, two heal spells on the same unit is too much.
9. Two units with the same spell: Defend.
10. Lightbolt does not teleport the caster.
11. Two heroes with the Shockwave spell. Most spells are just Warcraft III copies. You should try making custom ones using triggers or importing some:
Spells | HIVE
12. Some upgrades and other descriptions need to be better. This is a good tutorial on how to write a proper description:

13. Flash Heal, Mend and Heal all have the same icon. Too much healing in general. Balance the abilities accordingly.
14. The Cleric is too fragile. It's a joke: 75 HP, 0 unardmoured and Very Slow movement speed.
15. Blessing and Inner Fire have the same icon.
16. Holy Weapon should have melee range. When trying to cast from a higher range, the unit misses but the mana is consumed.
17. Hippogryphs and Archers, we've seen this already on the Night Elves. Plus, they're weaker than the Argent Dawn Archers which can be trained earlier.
18. Holy Arrow doesn't fire with each shot. It's not an autocast spell.
19. Why do these archers have normal attack type? Another weird thing is Paladins having Pierce attack type which would make them useless against Grunts, Footmen, Abominations etc.
20. Blessed Weapons looks like it's an active spell. You can make it look passive if you want with this:
BLP Lab v0.5.0
21. Summon Geist looks like a green square. It has no icon. Learn about icons here:

22. High Lord of the Ebon Blade's description has issues: " " " " " ", stuff like that.
23. Bone Gryphon has no attack projectile.
24. Blessing is replaced by Beacon of Hope and Vice versa. So, happens with Inner Fire. With the new patch this problem will be solved, hopefully.
25. Two heroes are exact copies of Warcraft III melee heroes, Tirion and Darion. The latter should be placed somewhere else in the Acherus, not between normal units.
26. The Acherus can't be moved. Then it only raises dead when troops die in your base, near it? You shouldn't summon it in your main base because it might appear somewhere you don't want to and will block the way of units....
27. Why do the farms have mana?
