JP has never had a 7 unit banner. This banner is potentially (unless Gumi deviates from its normal gacha distribution policies) the worst ever, because it would imply that Garnet (the 4* base unit) would have a lower draw rate than 5* base Lightning on banner.
If you mean trash = 4* max, than no. According to the Reddit Wiki, all FF13 units awaken to at least 5*. (Lightning, Snow = 6 *, Fang, Vanille, Sash, Hope = 5*)
Because its actually fun, despite the BS that Gumi is pulling? I derive my fun from making teams work that should have no possibility of succeeding (at least in the opinion of the hivemind on Reddit) and playing characters that I actually liked from previous FF games.
I think Shouta on the last page was discussing a recently released strong dagger with innate dual wield. I want to say that it was called the Cowboy Dagger/Dirk, or something like that.
