100 seems fine to me personally. When I was farming my mount, I remember seeing far too many people up in the 200-300 run range which is horrible. It's nice to still have a bit of a "challenge" (getting lucky on RNG) with a fail-safe in place.
I was in the 100+ club myself on getting the drop, just in case people are thinking I now don't care since I have my mount. I'm going to start farming the next birds and am thrilled to know it will only take 100 runs or less![]()
