Dont worry, they split you up into 2 groups here. The Priestess of the Moon continues insided with some archers, and the Keeper of the Grove continues in the cave with druids. Kind of sucks, but it happens and at least if you were down to no units this lets you start over. Also, this shouldnt be a spoiler, but as the Priestess said she is going inside to free Illidan, and he is perhaps the most kickass character in the entire game. He only gets one mission though, but it's a good one.
Multi player (especially against the computer) the combination of Priestess + Keeper is a real killer, especially if you can get a necklace of spell immunity. Take hits with other units, and stand behind them with healing and starfall.
Only thing I like better than that combo against the computer is Undead. Undead sucks when you first play it, as it requires a different play style, but with banshee with all upgrades (possession) and Vampiric Regeneration level 3 + Unholy Aura you are almost invincible. Especially against humans. Possess a peon and get him to your base safely (gotto walk back, can't recall possessed units), build town hall + blacksmith + barracks + altar, get a castle and upgrade all melee skills, get a paladin as third character and build knights. Protective aura + all upgrades + undead heros will give knights with armor class 15, faster speed/regen, and 45% regen from the damage they deal. Use sleep to knock out special abilities of enemy heros, surround them and kill them first. Heal the knights with the paladin, and the vampiric regen guy with the other undead hero. Make sure you have a few crypt friends to bring down enemy flyers so your melee units can take em out.
If they all hit level 6+ you can stun enemies with the inferno, resurrect your units, and raise the dead.
Sleep/Vampiric regen/Inferno are better to my opinion than the Keeper's powers.
As for the single player part: Just keep playing. It's annoying a while, but you'll get past that, and the final level is rocking. It is possible to do the final level without losing a single defensive line, but it's extremely hard. Try to make it
(Hint: Start on a second mine immediately, to double your income. Third if you still run low. Build a new base in the human base at the bottom. Use Starfall on the heaviest attacks, the healing one on the softer ones. Stock up on archers.)
Note: It is not possible without cheats to actually take out the bad guy at the end, so don't bother. He can wipe out all your units in a few seconds without getting hurt if you really insist on attacking him. If you kill him he is immediately resurrected (few times max).
