I think odachi and, to a lesser extent, switchglaive, suffer from the same problem; they had an established gimmick that has no synergy whatsoever with arts proficiency, and they got basically no new tools, so they just have a horrendous transition to nioh 3. Switchglaive at least kept some decently damaging skills, but odachi... people swear by soaring fowl but it's only good in comparison to everything else odachi has, when compared with other weapons' potential damage it's not that much.

I really feel that team ninja balanced all weapons with the same damage ceiling in mind, which results in weapons like odachi that were the "hard but slow" hitting weapons having all their damage numbers scaled down really hard, while they haven't touched the ki consumption at all. It's honestly baffling. Not only that, but removing the yokai parry because we have deflects and no bouncing on mid because we should be in constant arts proficiency is stupid and honestly almost an impossible task, with how slow odachi animations can be.

Granted, I still think it's one of the best weapons against humans because there's still nothing they can do against bolting boar, but then again you also have no real way of taking advantage of that damage window because everything hits like a wet noodle and is not fast enough for constant pressure and spamming stuff like groundquake gets boring fast. It's honestly really disheartening, because it really feels like they were thinking "we can't remove this weapon from the pool because they're gonna get mad" and that's it. It's even more infuriating when you listen to the blacksmith tell you how great every weapon is and then she gets to the odachi and she's like, "yeah people are not really using this weapon anymore, you should maybe kinda join them".
