The Death Arena

Hi, I have a map called The Death Arena, now it can be considered to be completed, but still need to improve and I am adding items.
This is a Hero Arena map, consisting of 15 heroes and numerous items with recipes, over 100 items to buy and about 34 recipe items to combine, hope you all can be my testers and give me some good advises or helps =)

This map is a definition of imbalance.

I don't mind str/agi/int tomes, but hero level tome and hero damage tome are just insane.

Half of items are useless because tomes are better than them.

Advice: In maps that has tomes items should give abilities that cannot be got with tomes.
So if you have str/agi/int/dmg/hp tomes it is pointless to have items that give you this stats.
Items should generally give you abilities that cannot be got with tomes: lifesteal, windwalk spell, invisibility detection, evasion...
Generally you should have less items, but make them better.

Terran is abominable.
Creeps have no theme, pure random madness.

In short you still have to work a lot to make this a decent game.
