New units. Their discussion and selection of upgrades.

It depends on who you're going to use them against! If you're going to fight high-level troops, then definitely choose the new ones. If you're going to fight archers and units with low defense, then choose the old ones. I think you should consider the situation: the opponent's race, the stage of the game. The old grade definitely rules in the early stages, and in the later stages, I choose the new grade! By the way, if you're attacking neutral creatures like black or green dragons, it's better to choose the new grade! IMHO.

P.S. If your sworn enemies include units like Riders or Vampires, I think it's better to choose the old grade, but if you're playing as Osiris, definitely choose the new one!:smile54:
