Sup Stylo, i hope you are doing well and that you are still working on this map, it is one of the best custom maps after all.
I was watching Wtii play this map and this thought came into my mind, I think the map gets a bit too predictable, especially after you played it or watched it being played by someone a few times and since this map is heavily based on the replayability aspect i believe it lacks that extra thing to make it feel more fresh each time you play it, so here are some suggestions:
---- There should be some extra events

that happen at least once during each week like this:
- This would be called the Clones Event:
It is clear that all the waves look pretty random with random creeps but i would love to see certain waves having only 1 type of unit (as example a wave of 13 ghouls, or 10 archers, or 3 mountain giants, or 10 sorcs, etc.)
- This would be called the Random Faction Week Event and Special Themed wave Event:
It would be cool if certain weeks have random themes to them (as example, Undead week, where every wave has only undead units and the final wave having an undead boss as well, even the rewards like the items can have an undead theme as well).
Talking about themes, i think it would be cool if there were waves in some random normal weeks that have a special theme like a Starcraft theme wave for example, where one entire wave is made out of zerlings (like 15 zerlings for week 3, wave 5) or a wave of 5 marines, i think this would be fun. (The zerling and all the other starcraft units can be found in the war3 editor, i think they are fun and easy to play and be used in this map without breaking the overall micro theme.
It can be used for the final wave in a week as well, for example having 2 hydralisks for the boss wave.
Other themes for special weeks or waves: Naga theme, Fel orcs theme, draenei theme, etc.
- There should be some random boss waves that have heroes as well replacing the high level units, for example for the first week there can be a random level 3 Hero, and the higher the week, the higher the level of the random enemy hero would be, the enemy hero can have some extra items as well, stronger items for later weeks.
This can go hand in hand with the previous themed events thing, for example for the undead week event, there can be an undead last boss hero at the end of the wave.
I hope my suggestions aren't too crazy or out of the blue, and that you will consider them.
