Orcs versus High Elves.

Elves are a very complex race, not for beginners. It took me about six months to learn how not to lose troops to neutral creatures and to start quickly. Walking neutral creatures (like armored warriors, minotaurs, orcs, golems...) are easily defeated by fairies, as well as by furies (although it takes longer; fairies are quickly defeated, so you have to fight them manually with the hero). By the beginning of the second week, we already have a sufficient number of archers, and even on veteran difficulty, you can upgrade them early. And after that, everything becomes much easier. It's not worth saying that elves have a losing start. Yes, there are some difficulties, but you can learn. Try to avoid such categorical remarks, like elves are always terrible against orcs, because you might be considered a fool.
