Which faction is the most interesting to play as, and what strategy do you find most engaging?

My favorite strategy when playing as the Barbarians is to gather as many Cyclops as possible! It becomes very fun! Especially when an entire squad of your own Vipers dies from their attack (this has happened to me twice already).

Funny, but I have a similar thing happen, but only with dragons and with the Knight Isabel (this has happened to me many times).
But I won't stray from the topic; I think that all factions and strategies are very good, and I personally think it's a matter of taste, and it depends on what is more interesting to each player. For example, when I play as Dungeon, I always train Chaos magic, Luck, Logistics, and War Machines:D. And when I play as Necropolis, in addition to all of that, I also add Summoning magic:D.
