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

What I like about discussions on such topics is that you learn a lot about other factions and then choose them and test whether this or that works. But tell me, what makes Elves stronger? I wanted to play as them (I like archers (3)), but I never learned how to use the Avenger. Luck, with the help of artifacts, also works well, enchanting is a long and not very exciting process, but what makes them stronger than Necropolis?
