Problem is that I don't use Muarim or any of the Laguz at all but I really thank you for this, I'll certainly keep it in mind for a second playthrough.
-I guess that giving Ike both Wrath and Resolve means taking out Aether, so I'm kind of skeptical since it's my first run,
-Guard I'll probably give it to Jill since she is ususally one of my units that takes on most enemies.
-Thank you for telling me that about Gamble because I haven't used it and I really wanted Kieran to be more usefull
-Smite will probably go to Gartrie since he kinda ends up behind most of my units after a few turns for at least he can push them a little bit.
Thank you both for the advice.
