Part of me says yes, while the other says no. Yes, he did given novice players including myself in Mahvel 3 with his YouTube series Assist Me and one of the most positive player in FGC, but we shouldn't let our personal feelings get the best of all of because
Of his ignorant remark of DOA and I can't judge him because I was once like him once I gotten back into playing DOA5 and the series in general so give him a second chance and if he still has the mind frame of DOA being a game of boobs and fanservice then show him no mercy.
