New units. Their discussion and selection of upgrades.

I always used classic upgrades for the Light Elves. The advanced upgrades for this Faction aren't that great.

But that's a mistake.

In my opinion, the new Light Elf units completely disrupt the balance.

The new Druids increase magic power so much during battle that the hero becomes an incredibly powerful Chaos mage.
As a result, the Light Elves, already having high defense and knowledge stats, also gain a magic stat comparable to that of a Necromancer.
All that's left is to boost their attack with artifacts, and we have a hero with stats that other races can only dream of!

Nymphs allow for such beautiful manipulation of the AI. Just buy at least 4 Ents for the army, and the symbiosis will ensure we have no losses!

Wind Dancers – I think you haven't seen how high the defense of a squad becomes after running from one side of the battlefield to the other; otherwise, you wouldn't be so confident!

Archers – I don't even need to say anything; it should be obvious.

When Enraged, Ents increase not only their attack (sacrificing defense) but, most importantly, also increase their initiative by 5 points!
So, considering the attacking style of the Elves, Wild Ents are clearly better than Ancient Ents (after all, +5 to initiative is too much!).

In my opinion, Unicorns are still better in their old form.

However, Crystal Dragons, with high luck, can be considered one of the strongest units in the game (although much depends on luck here)
