I've been trying to decide for a while what I want to do about NepDra's latents. For my Gabriel team I decided to go with mostly stat boosts because that team has a lot of stat modifiers, meaning that I get double or even quadruple duty out of each stat point. Right now the plan is this:
Gabriel: 5x RCV
Reine: 5x RCV
Snow White: Unknown, but possibly 3x HP+2x Delay Resist or 2x HP+3x Delay Resist (none of her stats are really high enough to take full advantage of stat boosts)
Sun Quan: Rainbow resists (he's on multiple teams, so Ra can also use his resists to fend off 100% gravity. Then again, Snow White is now on even more teams)
Beyzul: 5x HP
It's worth noting that one of my common Gabriel pairings, even though it isn't optimal, is Gabriel/I&I. When I use this team the RCV boosts are nearly completely wasted, since it almost always overheals anyway. Because Gabriel/Gabriel and Gabriel/Ryune are more optimal I structured the resists with them in mind, but I don't always use them.
My NepDra team has a lot of overlap with my Gabriel team, so it will inevitably look similar:
NepDra:

Reine: 5x RCV
Gabriel: 5x RCV
Snow White*: Whatever I decide to give her for the other team
Alrescha*:

*Either of these two can be swapped out for Awoken Orochi situationally
My first inclination is to give NepDra HP boosts because he has huge HP and that will be more useful if I need to use him as a Gabriel sub (although that has yet to actually happen). My logic is kind of that I've already not committed to rainbow resists so I might as well not start now, but then again do they need to be stacked to be better than HP boosts on a team without an HP multiplier? And I also don't have a rainbow resist member on this team, so I might want one for 100% gravities, and I guess that could be NepDra himself. I'm not actually that worried about 100% gravity here since I can just burst past anything I don't like the look of, but it might be useful to be immune to them for stalling if I need to recharge my skills.
Every NepDra friend I have right now with latents has some combination of element resists. Only one of them actually has rainbow resists, one has all dark resists and one has all wood resists. Will I be shooting myself in the foot for potential team dungeon pairings if I don't get resists too? Do people get that picky about who they pair with?
