I didn't play it, i said i recommend
you playtest it to see if it works.
I tried opening the map.
You have a lot of things to fix:
-Creep drops are not balanced at all, check
1v1 maps in the competitive pool for reference on how to balance drops.
-Gold mine creeps have camp aggro, when it should be aggressive aggro.
-Too many chokepoints near the mana fountain
-Lots of creeps will draw aggro when you send units past the amp.
-Creeps block the path for scouting units
-Shops are basicly free and are too close too each other, a player could easily amass 4 healing scrolls and GG.
-Base ramps are not good. I made ramps larger and added a secondary ramp to make the ramp concept function better. As well as rocks to prevent cannon tower placement.
-Lots of unused areas without trees.
-The center goldmines are pointless. I changed them to laboratories in the fixed version.
-Fountain of mana presents huge imbalance issues with mana hungry heroes.
-Lots of holes in the trees. Check pathing with hotkey P.
I made a rough draft of changes that would greatly improve the map and make it so it actually gets accepted. I leave the polishing up to you.
