True she is the healer so it could be false statistics based on more people picking her. Though with Ast being a rogue... perhaps if we know the numbers of people playing her vs. the others we could make a more informed decision. If she is being used 85% more then the others, do to more people playing rogue then cleric, or fighter then cleric, Gale and Wyll can be interchanged difference is personal bais on which you prefer in your group. Wyll can survive a bit longer the Gale, but Gale is the more flexible.
