in my opinion the worst map, unfortunately. i expected a bit more :/
[+] didnt really support the idea of 4 heroes in this mission, although it makes the mission much easier to complete, but still a + for the blademaster hero, the skin is nice like also the replaced mirror spell icon for a human blademaster.
thats unfortunately the only 1 positive thing...
[-] like upper written already, 4 heroes are too much for this map. the blademaster, together with a dark orb is too overpowered. 2 heroes would be enough for this, or you could add at least 10 minutes more for completing the mission.
[-] the troll base has really little space for building. maybe it is the map itself that you can't change it but maybe you could delete the trees between those 2 bases and change the buildings position from the orc base so the troll base would have more space.
[-] the enemy always attack the troll base, my mate was only attacked twice. the western side was never attacked. you should change this.
[-] i dont really support the idea of nagas, i mean maybe for the non-warcraft fans it is unimportant but for making it more realistic you could remove them. at this time they still weren't there, as far as i remember, and they still served illidan.
[-] the one murloc hero is missing (the same from mission 4, final boss).
[-] troll base: treant worker instead of troll worker (?)
[-] what it makes also easier to finish the mission is the big choice of units, i think there are too many of them. the starcraft orc, the troll priest (it was another troll tribe anyway, but here my warcraft-fan soul is speaking through maybe
) and the orc rider aren't really that important for this map in my opinion.
i am sorry if this sounds like a very harsh critic for you. the positive things from this map anyway like the skin of the trolls and the buildings i already emphasized in the third mission forum, like the other positive things too. i am just a bit disappointed because i expected a far more harder map here, although the third mission for example was harder for me than this one. this has anyway a good potential and i hope you will be ready someday to edit it
best regards to you mate
