[Agema]

H2 priests can be very important for bless tactics whenever you don't have an H3 handy. You want to bless your troops quickly. If you've been recruiting H1s you'll need more, and they'll have detracted from you building national mages instead. If you don't have enough holy power you'll have had to put your sacreds and Hold & Attack, which limits their tactical usefulness or potentially exposes them to more damage from ranged attacks.
