@Miraglyth One big mistake from the NA version so far has been the lack of worthwhile weapons to hunt in XH urgent quests, there's alot of JP OT weapons that could have been converted into mid tier NT 13* weapons.
I did wonder about this, but I'm not hugely convinced. By mid-tier I'm guessing you mean "not as good as BIS" in which case, aren't you just asking for the income fodder drops to have a little more variety? I'm not sure how that creates entertainment. More to the point, we did have the v2 and Snow series in the last two event UQs, which while appreciably low-tier 13* weapons can't be that different to mid-tier 13* weapons when most people won't want to invest in either.
In that respect it would be nice if more of the weapons you listed were converted into weapon camos. We've got Flowen's Sword (Open Beta, but available on PC launch too) and Nei Claw / Nacht (PC launch), so the precedent is there. And if they're camos a fair few people might be interested in using them. That could give a little more life to UQs, but at the same time we already get some camos like this (Charleville1766, Cydstrid) and if they did too many at once it could be overwhelming to keep up. Maybe one or two more per event could be okay though again I'm not sure that really creates entertainment.
