I for one would love to see turn-based class combat. One example of a trainee:
Human Paladin Trainee:
*A basic attack that deal humanoid damage (crusaders strike).
*A bubble (divine protection).
*A heal (flash of light).
*An AoE that hits the current opponent and the 2 on that teams bench (shield of righteousness).
*A buff that increase your teams health and damage for a few turns (blessing of kings)
*A spell the deals damage to the active opposition pet every turn for 5 turns (consecration)
Dwarf hunter trainees could even come with bear pets! and Undead warlock trainees could come with one of the demon pets too

What would each race's class be? and give some examples of fun skills they could use in the turn-based pet combat system.
