Busily weaving

Fire Emblem: Fortune's Weaveactive

The lack of a weapon triangle definitely I think removes some texture. Sure, it's just rock paper scissors, but it means Cai can't just tank EVERYONE, an axe wielder makes you think twice. And sure spears do more vs mounted units but you can dismount for very free.

I think I'm also not using weapon arts aggressively enough but the game doesn't make me so...

Bird time is the silliest mechanic ever. Every time I do it I just think about how dumb it is in fiction. Imagine being a bystander for this exchange.

"Bird, do you ever think I'll be better than my dad with a spear?"
Bird sings a song
"You're right, I'll NEVER be as good as him. I'M A FAILURE! ...so anyways, today's a perfect day for fishing, you wanna come along?"
It is currently the middle of the night.

If they want to rip off persona so much just do it harder in the dungeons. Make it a one more system. Make it at least mildly interesting.
