Totally get it, juggling the Playables setup and daily updates is a lot for one person. Sounds like you're making good progress though.
I should be upfront about why I'm asking about content. I'm a professional video editor, and I cut short clips for indie devs. With 8 classes, Ascension, and Rift Trials, your game has plenty to show off. Things like class showcases, boss fights, and legendary drops would work really well as short clips, and having a few ready before the Playables version goes live could give you a head start on players.
If that's something you'd ever want help with, I take jobs through Upwork, so there's a proper contract and payment protection on both sides. Happy to send you my profile or put together a quick sample clip from your trailer or gameplay so you can see my style, no strings attached.
