18% (or approximately 20%) was equal to about a cure 2 on tanks. Outside critlo, this is nearly twice as strong as the shield component of Scholar, no risk of wasted overhealing, for the same GCD cost.

Stoneskin stacked with other shields, and if I recall, this change didn't happen until Heavensward, so that was probably a factor to make sure Astro had a place.
I don't think Graniteskin even really stepped on our toes too much, Stoneskin took an age to cast and was typically swiftcasted or cast at the start of the fight from what I recall. But it didn't tend to get used over other WHM heals except member in more niche situations whereas SCH's shields were its bread and butter and central to our healing kit. So I guess it could have been for when AST came out. Sure it meant WHM got a shield worth using, but hey, some circumstances need it, just like there are circumstances where SCH needs to be able to pure heal and had that tools for that...and then the devs had no qualms about SCH then stepping on WHM's toes in that respect by make it too good and pushing its shields into a secondary healing feature.
