Is is Easy to Solo With a Priest?

Soloing with Priests is typically very easy because of the high amount of damage they can cause with shadow spells, their healing abilities, and special skills that allow priests to fear enemies and buff themselves. However, soloing can be very slow for Priests before they get the talent Shadowform, which increases shadow damage and reduces physical damage taken. Also, soloing while holy spec'd can be much much slower than soloing while shadow spec'd.
