Tactics for playing against Wizards.

Considering that we are discussing tactics against mages, defense might indeed be unnecessary.
It's not that easy to outshoot mages, even for elves, and the hero will summon fire elementals.

To be honest, in prolonged battles due to these tier 3 mini-units
(mainly affecting initiative, luck, and attack for all ranged units), I wouldn't play as anyone other than Wingard.
