Warlords is great but I'm stuck on the high 80% difficulties, since the Human Alliance's dudes (Demon's aswell) get really hard to take down. Any tips? My race is Trolls BTW
The general strategy that always works unless the demons send two spear masters in a row with archer support is:
Get some swordmen going, and in clumps.
Support them with spearmen (they will catch up and their attacks will overlap)
Support that clump with TONS (like, produce them as fast as possible) of archers. They are so damn broken. Again, use clumps of units.
Although it takes forever and a say, save up for your rush on the mountain trolls. Unleash it and you basically get a "rape your opponent" card handed to you. Back them up with a few archers where the enemy defends heavily and they should be alright. Though a few may die if you're on the final levels (90%s). Right when your trolls have freed up a row or two, get scouts going. This is the key to winning. Spam scouts in every open row and you should get almost all of them through.
That's for offense. For defense:
Swordmen. No archers at all, as you need units that have some girth to them. All you're trying to do is stall till you can get a few units going and eventually your rush of mountain trolls. If you're in a panic, here's a simple sequence of unit production that will get you out of most situations:
1. Swordmen
2. Swordmen OR Spearman (preference)
3. Spearman
4. Spearman
5. Repeat
