The map is missing multiple elements crucial for it to provide a consistently enjoyable experience. The main flaw of this work is its pacing. The game is painfully slow as the towers are unkillable early on, spawned allied units wander randomly around the map and seem unable to reach enemy's buildings and thus aren't helping players at all, there is no gold reward for killing the units or destroying the buildings of the opposing team and the items are incredibly costly for what they offer. All this leads to almost an hour of unfulfilling gameplay which doesn't even result in victory, since you didn't even make a trigger for that. Without some major changes, this map is going to be yet another underwhelming imitation of DotA.
Towers should definitely grant gold to the opposing team when they are destroyed, same goes for enemy spawned units. The reward for killing heroes is almost nonexistent - it's more rewarding to roam the jungle killing creeps as they grant much more gold. Therefore, the reward for Heroes should also be some kind of base value, say 100 gold. The income players receive is also incredibly small - without getting any kills it's almost impossible for players to buy any item above 500 gold.
As for the items themselves, they are incredibly simplistic and unimpactful, especially when it comes to Intelligence heroes, who do not benefit as much from attack damage and attack speed. Most of the items are just taken from Melee and Campaign, anyway. Also, why did you rename Strength, Agility and Intelligence to Might Reflex and Sight? What's the difference? Does it matter? Some item descriptions still mention the regular attributes.
The ai or triggers of the spawned allied units should be just focused on getting to the opponent's base - simply make a trigger ordering them to a-move to the opponent's base when they spawn. Otherwise they are just walking around aimlessly.
Why do Heroes respawn where they last died? This makes no sense - this means that players can just camp at the death locations of others and kill them as many times as they want. Just make heroes respawn at the Fountain or the nearest allied tower alive.
The Mud Golems keep spawning indefinitely, slowing the game down and making computer-controlled units stop moving every few seconds.
There isn't much innovation in this map, heroes are basic and many of them are taken straight from Melee, they jsut have their skill icons changed, there is no boss like Roshan that could be fought in the late-game, the terrain is bland, and the overall gameplay experience is pretty negative. Without any changes, this map is just a simple edit of DotA.
Due to the map being in alpha stage, it is bound to be marked as Substandard. If you need ideas on how to develop your map, please head over to the Map Development forum.
