Funnily enough it was exactly the opposite for us. We had to pug a 2nd healer every week and Astros in party finder were, to be frank, not very good. The kind that does an octaweave every burst window, manages to misalign raid buffs immediately, do bad dps and somehow still manage to be less effective at healing the party than our Sage.
So we gladly took a WHM pug over an AST pug for P3S every time because it could completely invalidate a mechanic just like AST, the bell made a mockery out of Fountain of Fire, and the usually better dps allowed us to simply skip Death's Toll.
