What the title says; as it currently stands, Greninja and Greninja-Ash are lumped together under base Greninja on usage stats, which leads to misleading usage stats implying that base Greninja is commonly used according to the Gen 7 Pure Hackmons usage stats, when in actuality all of Greninja's usage is due to Greninja-Ash. Since Greninja-Ash is a in-battle forme change the only meta's usage stats this should really effect is Gen 7 Pure Hackmons. There's precedent to separating the two in usage stats, as all other in-battle forms (including Megas, Primals, Zygarde-Complete, and Necrozma's formes) are all separated, but not Greninja's.
