I am having a hard time picking a school. They all seem pretty cool but I am not sure what to choose.
Well, that depends on what your playing style is. In short, Ice has a lot of health and defense but lowest damage, Storm has most damage but least health, Death can attack enemies and heal at the same time with drains, Fire does damage over multiple rounds, Myth summons a lot of different minions, Life can heal, and Balance has a lot of blades and shields but also a fair amount of attack spells.
