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

Castles with a might-oriented focus (unless the player using them is suicidal) also have magic for buffing/debuffing. Sylvan, without Light magic and mass buffs, loses the ability to further strengthen its already not-so-weak army. Haven, thanks to having Light and Darkness as its main schools in the guild, can buff its own troops and debuff enemy troops. Inferno has dark magic in its guild, in addition to Chaos magic. Gnomes have Light magic and Chaos magic.
So, the Academy isn't the only one:).
