The most difficult alternative

Saint_Paladin, it's quite simple :) In Equilibris, which is what we're all playing online right now, Crusaders are much stronger! And they attack twice! That is, they have a real chance to kill a Hero! Imagine, under favorable circumstances, for example, near a Shrine, the Crusaders can easily approach the enemy hero and attack him, he dies, of course, he immediately revives (because he has immortality), and then receives another, fatal blow with a sword! :) Plus, it's problematic to cast any negative spell on the Crusaders; it will most likely be rejected!
So, it turns out that they are much more advantageous than Monks in many ways :)
