Indeed they are very formidable foes that even Ritsu's Dragon-Hornet swarm and Victoria's Magical GIrl army couldn't handle alone. If you include the Remnants that Daw Maw makes as well, his army is nigh-unbeatable even if the other 12 WS teamed up to fight it which is why other nations had to help take him down the first time.

Ultimate Superpowered Mooks in any case :D

Actually 300 hundred years ago, Huozai and Dark Maw had a disagreement about how to female captives and so they battled to see who's way of treating them was the best way.

Izaya only won the top rank because Ritsu doesn't use her Fire Magic or summon her swarm and Victoria has to hold back her full power being a witch.
