In your opinion, which faction is the strongest in Heroes 5? Let's discuss the advantages and disadvantages of each faction.

"However, you can attack those who are nearby, or you can simply fight them, since they are much less dangerous than the Knights of Isabel." The point is that the Paladins/Knights move very early and end up closer to the enemies by the time the enemy hero's turn comes – obviously, in this case, casting Berserk on them can only be done out of a desire to lose the battle. Again, Berserk can be countered with Inspiration (this has been done many times by the Knight and the Barbarian) – your unit is moved further away from the Berserk-affected stack, the Berserk-enhanced stack attacks the enemies, you spend 0.25 of a turn and 0 mana, or you simply put some "expendable" units next to them. In general, the main problem with Berserk is that the "protected" unit must be closer to its own units than to yours at the moment of the turn. And this is not as easy as it seems – all sorts of morale effects (especially with the presence of "Empathy"), fear, repulsion, in general, things that are difficult to predict. As for the fact that the Knights/Isabel are much more dangerous than the Paladins – that's WRONG! They are not significantly different in terms of stats; in essence, they differ only in one thing: the Paladins have "Ice Calm" (anti-Berserk), while the Knights/Isabel have "Tournament Strike," which is certainly useful, but any sensible opponent will, of course, do everything to prevent the Knights/Isabel from using it (it's not that difficult), or even better, to make them use it against their own units.
