I'd like to suggest a few things for the existing Harad map, specially the Haradrim creeps which were briefly discussed on Discord:
1- Creep units from the Haradrim camps are VERY strong, including lots upgraded swordsman, archers, pikemen, hero and towers. Because of it, it is not viable to conquer the camps on a real skirmish game;
2- Creep units doesn't seem to be scripted to "Guard" current location as they should (protecting their territory), so a player may bait them to anywhere on the map, and a player that tries to flee from the camp which he got inside inadvertently will take the very strong units to his own base, potentially meaning gg in the early game (as I've seen happening recently);
3- The special feature of conquering a Haradrim camp is nice, but I think it may be improved - only the spearthrowers can be recruited now (and I don't think they are balanced for Edain 4.x - they seem weak and expensive), the haradrim lancers and archers are not available even though their picture is shown. Perphaps Haradrim Archers and Lancers could be unlocked when a TEAM conquers at least 2 Haradrim camps (at the moment, there are 5 on the map, but only 4 have heroes and are conquerable).
