"Anyone else having some rotten luck with the Unova stones or are they this extremely rare?"

#PokemonGO: Despite doing the research breakthrough each week, getting the 7th spin most weeks and doing the leader battles daily, I've received 0 Unova stones since their release.Do Rocket battles have a chance to drop them either? I've fought several grunts and three leaders but still nothing.Just wondering if others are having this hard a time as well x) via /r/pokemongo https://ift.tt/365VuGT
