Answer to your question: Yes. Pro player who tested Arturo, Hektor C, SRK, and gameplay footage all point to him being a zoner. Just because he can engage at close does not mean he is not a zoner. That's like saying Deathstroke is not a zoner because he has a sword and can combo without using guns.
But hey, I get it, gospel according to Colt. Praise be to his opinion.
IMO, we should take this opinion of him not being a zoner to another thread, maybe classify BA as a hybrid only to validate the opinion. Someone get on it!
