I'm disappointed that Grenth didn't stay. Given this is the god of strict ethics it makes no sense to me that he'd ever leave his only home and those he watched over.
I was hoping for a twist reveal that Grenth had stayed and was going to reveal himself to help stop Balthazaar. Who knows maybe they still can, though, it does seem awkward at this point given the story so far is only one god stayed.
I worry the story is going to be the gods gave up their divine traits when they left Tyria. Balthazaar already said honor is worthless. And that really makes them feel like a waste or a missing part of human's culture in game. Just another big bad to fight so we can leave the dragons be for a bit. And what does that say of the traits and skills that are supposed to be blessings of the gods? Kind of hoping for a few less plot holes or at the very least not rewriting the gods to be petty.
