I was running through Lunatic to unlock Lunatic+ and in the map where Henry joins a warrior ripped him a new one and I didn't bother to reset. Only later did I discover I had unknowingly married all of Sumia's possible husbands except Henry! Poor Cynthia never had a chance :(

Owain is awesome, he has some of my favorite dialogue and he slays my foes

From my experience, unless you did a lot of grinding letting almost anything get attacked 4 times or more at once in lunatic or lunatic+ would mean one dead character unless the RNG loved you. Also, there would be no reason to pull a group that big to a solitary archer without backup anyway so they would still have a way out (you would want to mop up that many counter wielding units in one move, so they should have a few supporting units) Still I see where your coming from, it could happen but we gotta remember these units never operate alone they are part of an army :)

Pass for an archer seems like a waste of a skill slot to me, there isn't really a conceivable situation where they should be boxed in unless you do something weird like deploy them alone and run into the middle of a big group.

I really like snipers despite what I hear from a lot of places. 3 range attacks are just too great. I made Cynthia a sniper (Father is Chrom), her damage output is insane with Galeforce and Aether. She works very well tag teaming with other characters, she can kill something then swap, and the sniper's high skill stat means a higher support attack probability.
