At the same level a wizard's scorching ray would do 4d6 as a ranged touch no save so it doesn't seem that amazing.
The issue is one of how quickly each class can Nova. The Wizard is limited to two Scorching Rays (3 if he is an Evoker) and that's only if he has them memorized
For example, our group of 4 3rd level PCs fought a Young Green Dragon (68 hit points) on Saturday. Given a 3rd level Wilder vs. a normal Wizard with 2 Scorching Rays and 3 Lesser Orbs of Fire vs. a Warlock vs. a Sorcerer with 6 Lesser Orbs of Fire, the average amount of damage each round that can be done (assuming that the touch attacks hit) are:
Code:
Rounds 1 2 3 4 5 6 7 8 9 10
Wilder 22.5 22.5 22.5
Wizard 14 14 9 9 9
Warlock 7 7 7 7 7 7 7 7 7 7
Sorcerer 9 9 9 9 9 9
After Nova-ing, the Wilder, Wizard, and Sorcerer are out of power (except 0th level spells).
To do the same amount of damage, the Wilder used up all of his power in 3 rounds, the Wizard 5, the Sorcerer 6, and the Warlock 9. The Wilder does 67, the Wizard 55, the Warlock 70, and the Sorcerer 54.
Sure, they are all out of power (except the Warlock). For the Wilder, that's 33% of the Dragon's hit points per round. If the rest of the PCs could do that each round, the Dragon would be dead in one round. Even so, with a Wilder in the group, there's a good chance the Dragon would be dead in 2 to 3 rounds. The other classes cannot say the same.
The fact that the Wilder can destroy a powerful opponent so quickly also saves on other party resources like healing and other spells / charged items.
Edited to fix range and damage errors.
