The most UNPOPULAR faction in Heroes 5.

With Dark Elves, if you position the Furies strategically and don't waste them as cannon fodder in small skirmishes (as the enemy usually tries to overwhelm them first), you can inflict significant damage with a single attack... Plus, if the Warlock has summoning magic and can summon a Phoenix... then no Elves will survive... Their health is well over 1000, and their attack and defense are, let's say, considerable... It's a shame that their speed and initiative aren't very high... And Dark Riders are also a force to be reckoned with, and their lizards have a nasty bite :D, especially if the hero has the Tactics skill (although it's not the most essential or common skill for Warlocks...). And the Minotaur's counterattacks aren't completely useless either...
