Following numerous tweaks to the game's auto-resolve system, Mortal Empires' "End Times" event is, if anything, more of an anticlimax than in the first game.
A patch later made it a good deal harder.
Whilst the final battle is still a treat because of its insane visuals, atmosphere, Nightmare Fuel, and the power trip it is for the player (who gets to wield the sheer power of the Vortex against their enemies), the battle itself is rather easy, despite facing multiple stacks of armies belonging to every other race in the Vortex race.
