Shnurov and I were discussing this not so long ago. And, in fact, the Dread Knight is better than the Titan. The Titan deals 1/2 damage from the starting position. To deal full damage, a hero's turn is required. Either Accuracy or Teleport is needed. For the Golem to deal full damage, a hero's turn is also required – Teleport. That is, for this mediocre, fourth-level unit to become useful, a hero's turn is needed (for both). And the Dread Knight has much better stats. Therefore, we should build it. Besides, if I remember correctly, it's easier to build them.

Two Order heroes, one steals charms from the General, the other teleports the Titan into the enemy's ranks, and that's it.

This tactic isn't quite right. You enter the final battle with Immortality potions, right? Let's say you have 5 heroes, Titans, and Nagas. So, how many Immortality potions can you steal? That's right – 2. And the rest will remain intact on their owners. Well, and according to Murphy's Law, they will, of course, be removed from some runner and a weak mage. That's how a strong, fast Order hero's turn is wasted.

Life has an Angel of Light, General's Joy, the same General's Protection, and Regeneration – aren't these useful spells? Especially the Angel of Light. Oh, and there's also Resurrection (if the enemy doesn't have Dispel).

Life has Sanctuary. Period.
Everything else is good, but Sanctuary is much better than everything else available.
