Lyn, my absolute fave outa the FE games as she was my first lord ever so i still use her even if i have better heroes. my current lyn is a +2 merge def+spd- running her refined weapon with brazen atk/def with vantage. i was happy with her til now but then RNG gods blessed me with a free summon lyn on the new daily banner. this one was spd+res- and im having trouble which to keep. my current lyn is nice and bulky sitting at 31 def 29 res but a not so high anymore 35 spd. if i were to merge into the new one she would be hecka lot faster sitting at 41 spd and 27def/res.
old lyn or new lyn? if new, should brazen atk/def be kept or switched for something like fury putting 30 to def/res while bulking up spd bit more?
i do loss out on the superboon def but her bane spd makes her get doubled alot and ends up dying before she can go nuts with her sword
The thing with Lyn is that she really doesn't care that much about speed. It's nice for her not to get doubled, but it's not necessary for her to double since her Sol Katti comes with Brashperation when refined, so it frees up her B slot for something else, like Swordbreaker.
I'd personally keep +Def/-Spd (which is what my Lyn currently has), but that might not be the 'most optimal' choice for her, so.. I dunno.
