Broodman Frenzy [Need EU Beta testers]

This map is a remake of the Warcraft 3 map Footman Frenzy. Every player spawns units and you battle them in the center of the map. Your goal is to destroy your opponents buildings.
You can choose form which race to be the units that you spawn (terran/zerg/protoss). By killing other units you gain minerals which you can spend on upgrades.
There are 2 types of upgrades:
-Attack/Armor upgrades : they buff the DMG/Armour of your units
-Tier upgrades :you spawn better units of the race you have upgraded.
The map is ready and working but it is still imbalansed so I need your help. If you are from EU and you are sick of the top 40 maps you can play join me. Write a comment here to let me know. I will host the map so that you download it and then you will be able to host it yourself.
Post any IMBA strategy and bugs here
In the future versions I will add heroes so if you have original ideas about them let me know.
