Which faction do you like the most in Heroes of Might and Magic IV?

LET'S NOT BUILD BALLISTAS AND MONKS FOR THE HUMANS, BUT RATHER CYCLOPS FOR STRENGTH, TITANS FOR ORDER, AND MEDUSAS FOR CHAOS. BUT WHY? THEY'LL JUST GET BLOCKED ANYWAY... I REALLY DON'T UNDERSTAND YOU.

You really don't understand... We're talking about the fact that level 2 monsters are generally useless in the endgame, except on specific maps. Any of them. Even level 3 isn't always useful. Level 2 is used for clearing the map in the early game (week 1). Gathering resources, breaking through oracles, clearing some paths, acquiring some artifacts, defending mines – that's what level 2 monsters are for. After building level 4, you don't need to buy level 2 monsters anymore.

IT'S NOT ABOUT HAVING A LOT OF UNITS, IT'S ABOUT HIM HAVING THEM!

Are you suggesting putting units in a square formation against an opponent with Phoenixes? O_O Practice a little more.

WITH PHOENIXES AND ELVES, YOU'RE ALREADY KILLING THE HERO.

How can you kill a hero with elves? If he's standing in the front ranks, he definitely has at least 70 defense, and often even 100! And if the Nature army doesn't have a Life Mage, then the Phoenixes will either be completely disabled from the battle with Terror, or they'll be slowed down, sealed, and a Vampire will be cast on them so they don't resurrect.

REGARDING THE WATER ELEMENTALS - DON'T FORGET THAT DEFENSE ISN'T TAKEN INTO ACCOUNT, AND 275 HP DRAGONS DEALING 10-15 DAMAGE PER SHOT IS REALLY BAD FOR THEM!!!

How many Water Elementals do you need to kill at least 3 dragons per shot? 275*3=855 HP - so you need 55 Water Elementals. And even then, they'll quickly recover under the Vampire's touch, at the expense of your elves. By the way, it will be difficult for the Phoenixes against them in this case.
And you want to take down 10-15 dragons! O_o You need 184 Water Elementals for 10 dragons! Where are you going to get that many?...
