Ey hold on a second there you mean to say blizzard wanted the missions to be harder? But they shipped the game without properly testing them? Huh and so whats this difficulty blizzard was looking for exactly? Can you bring up an example of a mission on blizzard "intended" difficulty and how it should be compared to what we have in game?
You're actually correct, lol.
Yes, warcraft 2 needed so many more tests to ship proper functionalities for players to experience. But its sort of understandable, considering how weak computers were in 1995.
I still do remember having a computer around 2001 which took about 45 seconds to just load one mission in DOS.
I originally made DAIFE mod to showcase the real intended difficulty for war2:

Just recently made DAE which is far more loyal to the original idea to showcase original difficulty intended by Blizzard, which is still harder than base game everyone knows about:

For example, Human10 mission you experience no more than 2 early group of transports with like 2-3 units (grunts & trolls) level 1. Maybe one random destroyer around and nothing else the entire game. 100% passive.
This one you're expected to face level 7 bloodlusted ogres and level 3 death knights. Attacks with transports and ships around each 4-5 minutes. None of these ever happen.
Overall the issues with the original AI is that they almost never upgrade and fully upgrade their units when its intended. The experience changes a lot when computer upgrade their stuff.
Xorc3, you face attacks with mostly grunts level 3, but it was intended to fight fully upgraded blood lusted orcs in level 8. Even to fight against Runes. In DAE mod for example, you can now face not only level 8 ogres but also Runes. A spell that never worked in base game for computers, but now its possible thanks to @ Mistral code.
More missions..
Human12, you fight against a 2 grunts transport attack early on... and maybe later at most you just face few 1-2 random destroyers or giant turtles at most...
You here were intended to fight against level 8 ogres in transport attacks each like 6-8 minutes. And fully upgraded ships like each 5 minutes.
There're certainly way more missions but cant remember at the moment.
Xhuman6, a legendary mission that always liked from dark portal humans campaign... Orange orcs get usually stucked very early on trying to build their ogre mound and never launch their attacks. They almost never work as intended but they were planned to launch fully transport attacks with level 5 units each like 8 minutes and fully upgraded ships.
They dont upgrade anything without the fix. The difficulty changes a lot this mission if they actually attack.
There're hidden AI scripts that never were seen because either they didn't work, or they were set in computers that are destroyed so early on, or not used.
Examples, like a Blue player in Orc14, which now has its usage in Orc14. I think they had upgrades till paladins tech.
Xhuman4, white player has up to level 5 ogres and fully upgraded death knights. Now you're up to destroy either Red or White at start, but not just killing white right away so you get a chance to see White AI in action.
Xhuman5 had a small AI script for green but never seen. Now it can and they're an active player even after start.
Xhuman8 early AI script for white. It can be seen now as an active player.
Have fun if you give the mods a try either way, bud.
