Copy and pasting my thoughts on the broadcast from another social I'm a part of:
That was a really good Heroes broadcast.
Lute and Joshua are among my favorite Sacred Stones characters, especially the latter, so I'm glad they're finally getting their chance to shine in Heroes. The latter being a Tempest Trials reward is cool too. Hope he has some solid skills and stats.
With Joshua in Heroes now, the only Sacred Stones character that I really want in the game at this point is Forde, but I guess I'll have to wait for now.
Looks like they're trying to make those spread-damage abilities more useful by lowering their cooldown, but I'm not sure if they'll still see use.
That weapon refinery mode looks cool. The fact it makes weapons stronger and can boost a unit's stats is solid, and I can already tell it will change the meta into some interesting ways. The cost to upgrade the weapons is quite expensive though. Hopefully, arena mode will provide a good amount of those necessary materials.
Also, my boy Takumi is among the units that can get a legendary weapon upgrade! That's awesome! Perhaps this will be his chance to reclaim the meta spotlight!
The most hype part of the broadcast for me was the Book II trailer. I always liked the Awakening and Fates cutscene style, and here, IS really brought it to full effect. That was EPIC!
Fjorm looks cool and pretty, and I'm happy she'll be a free summon. Here's hoping she will turn out to be an intriguing character to enjoy. Sutor kinda gives me Lu Bu from Fate/Extra vibes. The other two new characters look solid as well. I'm curious to see how will Veronica factor into this part of the story, though I wonder if we'll see the Book I story with Loki resolved before Book II comes out or they will save that for a far out future update (Loki seems like final boss material for some point in the story).
Also, was I the only one reminded of Gilgamesh's Gate of Babylon at this point in the Book II trailer?
I mean, Fjorm summoned those ice crystals Gate of Babylon-style, wouldn't you say?
Now I want to see a battle between Fjorm and Gilgamesh from the Fate series.

As for some additional details, we now know the names of the other two new characters shown in the trailer. The woman wielding that flaming-sword is named Reyvatein, while the big-chest woman is named Loki. Yes, that is the same Loki that was shapeshifting as Anna up to this point in the story.
Here's Loki's official art:
