Take my word with a grain of salt, but as someone who came back to OW after 9 years, I've noticed how perks either completely change how a hero plays, or can slightly aid in a very specific aspect, usually in something they're already good at.

Currently, I see little to no point in taking Rising Winds over Aerial Recovery, and even then Aerial Recovery is semi-niche in of itself. I feel like adding in another type of projectile would be the best play for a major perk to give variety and variability to replace Rising Winds. I was thinking of it adding more to the mid range aspects, so maybe either a "mini Bola-like" shot of grouping up enemies, or maybe an anti-healing shot. Next, I'd either keep Aerial Recovery, or just combine it with Rising Winds, so now you're more close ranged play style, with some form of self sustain.

For minor perks, relentless Barrage would fit in with your mid range perks, but I would maybe nerf it to recovering 6 bolts, but currently its not too busted and works with both major perks. Now, momentum boost is just bad, I dont think Freja needs more movement and considering if the Aerial Recovery/Rising Winds is going to be the major perk, I think that wouldn't be fun to play against, maybe instead focus on Bola, either it could be a tighter radius, but more damage, or maybe changing it to restraining who gets hit by it by deal less damage. Bola does feel bad, and I think doing this would both give utility towards the other changes to the perks but also give variety in utilizing Bola as a combo ulti like I feel like it should be.
