I'm torn on using her for skill inheritance since she has 2 great skills, and unsure about putting her on my armor team, since I already have grima, Hardin, zelgius, and Amelia on it
suggestions?
Unfortunately, -SPD LA!Lyn isn't that usable, since her main strength is mostly canceled out (unless you use QR and Iceberg/Glacies). If your armor team is fully built and you have as much Armor March as you want, I would save her so that you can give Guard to someone you like.
Atk/Spd Bond would probably be good on one of your tanks that doesn't have particularly good offensive stats but would benefit from the boost, like Sheena for example. If you can't think of anyone right now, wait and keep her until there's someone you know would benefit form inheriting her skills. (Heck, Blue Gift+ isn't bad either. :))
you have any speedy glass cannons you like? atk/spd bond would work wonders on any of them.
I believe even healers can make use of it, if you're planning on building any monstrous healers, since they cant use the more common stat a-skills like fury or LnD. Similar to the ones on lu bu feng xian's channel.
I really think that you can still use your Lyn. I have a +Atk/-Spd VA!Lyn that puts in massive work.
If you think about it, her Atk/Spd Bond puts her at 38 Spd when adjacent to an ally, which is pretty good at avoiding some crucial doubles. This should be easy to pull off in Armor Emblem because your Armor units will more often than not be adjacent to each other anyway.
If you give her Blarowl/Blarowl+, then she can get up to +6 extra Spd, which puts her at 44. With a Spd-refine Blarowl+, you are sitting at 46 Spd, and the Spd+3 seal will bump that to 49! (Even if you don't have that and decide to go with Blue Gift+ with Spd-refine, she's going to be at 40 Spd--or 43 with the seal--if you are adjacent to an ally, which is not bad at all.)
