Odin and Ophelia's A-rank conversation is rather sweet, if Awakening fan-service is your thing (which is likely is if you've stuck with Odin for that long).
I'm finding on Conquest that throughout the whole game I've been getting heavy mileage out of high-speed magic users, thanks to the abundance of enemies with low Res. For a while it was Felicia with the Flame Shuriken, then Niles picked up a Shining Bow and started mopping up everything in sight. And now it's my Ophelia. Double attacks with high-crit weapons = more crits.
It's also interesting to see that the new weapon triangle interactions with tomes, now pigeonholed into the same position as swords, has created room for a superimposed magic triangle where weapons like the Shining Bow really, well, shine. Lance/shuriken users designed to be strong against magic via avoidance rather than Res are all over the place in this game, and with the Shining Bow they drop like flies. (I suppose the same must be true of the Bolt Axe as well, but none of my axe users have a Mag stat that makes it a remotely viable option. The value of my Malig Knights is in their balanced Def and Res, not their ability to prick the enemy with fire.)
So, Ryoma hit Max level. He's already a promoted class, so... What do I do with him now?
If your staff shop is at level 3, there is a seal that raises the level cap.
It's not ridiculous. Corrin makes a choice based on his/her emotions and has to live it with it, despite realizing early on that it was wrong. In a last ditch effort to set things right, he and Azura come up with a contrived solution that feels more like grabbing at straws than anything else. Conquest is not a story about being the good guys. Conquest is a story of desperation, and the consequences of being unable to leave behind the kind family that raised you.
Yes, this. I picked Conquest for my first run because it was billed as the old-school, limited-resources route, but in terms of the story justification for the choice, I didn't mind at all that the prologue chapters completely stacked the deck in favour of Hoshido. The player is new to the world and all the characters so it might seem like Hoshido is the obvious choice, but if you are Corrin, it makes sense that you wouldn't want to let go of the people dearest to you who made you who you are. (The training sequence with Xander was an especially elegant way to present a tutorial.) Everyone draws a line somewhere as to what they are willing to do, and for the Corrin who sides with Nohr, that line is drawn at betraying the people who made him, with whom he has a conscious history. And I think there's a strong argument, fantasy tropes aside, that nurture trumps nature when it comes to who your real family is.
Haven't played Birthright or Revelation yet, mind you.
