SilverFaith said:This assumes you roll the spells. And this might just be me, but I very rarely get the spells I actually want on the priests.
Priests, however, in terms of survivability, are harmed in an entirely different way when placed in a unit. You might claim "It is just skinks!", but if you hit the large template and wipe out the unit,you still lost potentially 195 poins if you gave it a dispel scroll, and still haven't used it.
I don't really think you can compare them though, priests and trogs. Priests can be rendered completely useless by poor winds of magic, especially when you also have a slann, while a Troglodon will always have its use.
A troglodon is basically a transformed priest that can no longer cast spells, but still act as a channeller and range extender for your slann. I'd much prefer just taking a troglodon, rather than take a priest and hope I get the transformation. I don't know about your luck, but a 1/6 chance to get the spell isn't exactly good odds.
Fortunately,, Skink Priests have two guaranteed great spells: Wildform and Iceshard Blizzard.
