The battle was epic and allowed me to see new aspects of the game mechanics in action, although it's unlikely you'll achieve such an effect in a multiplayer game against a live opponent.
These aspects are old; in multiplayer, everyone still plays the standard strategy of focusing on damage output, using Vampires with Blade Dance, Magicians with Blade Dance, and other similar tactics. I don't understand what this has to do with identifying the strongest unit.

It's better with level 2 Spectres, right?
How so?
