Seems like they have refined a lot of mechanics originating from World. Hopefully slinger won't have the same softening mechanic as in Iceborn. Switching to secondary weapon might be awkward with armor sets usually specialising.
They have also uploaded two more info videos; one on focus mode and one on Greatsword. Guessing that more weapon showcases are coming up this week/month. Greatsword additions look dope. I'm eagerly waiting for my mains Hunting Horn and Gunlance to show up.
