Cool. Ok looking at them some thoughts are
Roy: Overall not bad if you’re going for a more budget build (I’m guessing they both are). 40 speed is nice although I’m not sure if it’s necessary with his QR refine. I guess it helps him avoid getting doubled. And 32 res seems a little low to ploy with these days.
Chrom: Again not bad for a budget build. +Spd is interesting but doable. I might suggest a bond in his seal to go with Falchion refine. Possibly spd/res bond since he’s kinda lacking in those stats (res is especially important if running DC after all). Also while s good special, Aether may not be very useful if he doesn’t have any kind of cooldown reduction. Since he won’t activate it much.
