IVs from egg have been severely lowered lately. The chances of getting "Best of the Best" is slim these days. Not happy about this BS more than the not getting free Incubator. What's the point of egg-hatching these days if all we get is as shitty as the garden variety of wild pokemon?
The small chance of getting a rare Pokémon I guess. I've gotten several Pokémon from eggs that I've never seen in the wild (Grimer, Chansey, Lickitung and others).
