Protect the Paladin needs balancing

[DemonBlood]

So this map works by having the Paladin start each round by going to a beacon, like many copies of "protect the queen" maps. Each player chooses a unit at the top, including the paladin owner. And they fight, which gives them gold and energy, and so on. It has real potential in my humble opinion. I've put a lot into it.

The problems come from imbalances in the game. The units picked vs. the units attacking are unequal. I don't know how to balance it from here. Other than just starting completely over, which would be a pain. Having said this, I would like some constructive criticism of the map. Please help and play with it. You can look at it in the Wc3 editor and see whats what.
