Self+1ally elem+ (+35%) fire res+ (+50%) 3t [6] -> 40% (why even bother?)
Self+1ally heal 2000 (333/t) + +25 burst [6] -> +30 burst (5 more burst can mean 1 turn faster, pretty big buff)
Self+1ally combo+ (+30% dbl +20% trpl) [6] -> 45% Double 30% Triple (fair buff, still doesn't compare to Awakened Titania, but +25% Combo is nothing to scoff at - especially since this gets you past 100% Combo with Tiara set bonus!)
Overall, pretty damn big buffs.By herself, I agree. There's a big, big discussion about her in Miracle Ticket thread some pages back, including a fair amount of math if you're interested. However, once you combine Saraswati with upcoming Vohu, Water teams become pretty damn fast. Neither of these Hime do it by themselves, but combined, they're quite the combo. Add in Shingen in there with her new, Second Anniversary EX skill and you'll have a suuuuper fast Water team.For Regalia usage, why not both? I mean, you're guaranteed 3x Regalias every day from hosting a Ult Disaster and 28 Regalias from the fragments per month - at worst. That nets you... 118 Regalia per month. You can LMB a weapon in just a month and have all the Regalia you want for FLBs in like two weeks. Six weeks in Kamihime is nothing. You do have a Union you can beg to kill your Ults for you if you can't do it yourself, right?
Also, in regards to Soul weapons, we're moving on to Age of Shingen soon enough. While Hercules won't be bad even afterwards, I should update the Soul thread... anyway, the point is, Herc might not be the best option anymore. If you're struggling with debuffs, she probably is though.
