Trying out a run of this to see how it goes. On chapter 2 now, and have noticed a couple things:
Like some other people mentioned, Ike’s starting weapon gets removed just like the Trainer sword does. If he’s a pegasus knight or wyvern knight this is just an inconvenience since you can get him a weapon later on, but I imagine if he’s a hawk or raven this would make him unusable for the entire game.
My Titania ended up as a sage, but can only use Wind magic. I know enemy mages are this way in-game, but I didn’t know if this was something you intended on the player end or not (or if it’s something you can even avoid for that matter).
I’ll try and mention anything else worth noting as I find it.
