Discussion of the Academy faction (Mages and Wizards). Tactics and their specific features.

I think light is still better. With darkness, you can counter one unit, for example, with a berserker, but Wing (and generally, elves at that stage of the game) usually have all their attack units, meaning the remaining 6 units will still deal significant damage. With light, you can immediately strengthen your army, for example, with a stone skin, and use mini-arts to withstand Wing's attack. However, even if you have a sharp mind, IMO, Wing's larger army will still attack before your caster can act.
