That's for if you want a universally applicable build. And after all, that's the definition of a meta anyway, gotta go for the most optimal picks.
Besides, I'd note that I focused the scope pretty narrowly to prove my point of debuffs aren't exactly vital. In that case, I might have made it sound like thou shalt pick only light, so let's see what options we have for other elements.
Fire is a pretty good current example of that, and future inclusions like SSR fire Amon only serve to cement the idea further. Oh, and Amon's another example of a good buffer. Fire Mammon becomes sorta a burst slave, but that's not really too bad considering burst isn't given the finger as hard as debuffs are.
Wind will continue to do wind chain burst things, but now everyone is a Herc with the inclusion of Azzy AW... which btw if you haven't seen what she does, give her DMM entry a read. I creamed the first time I saw it.
Thunder has some good options as well. Now I know you'll have issues with thunder Aphro, but vigor + heal + barrier is a really good way to deal damage. And end the fight quickly. Baal U is a semi debuff slave but her combo+ should be decent enough for her to catch up on burst and not be a deadweight. Raiko is... you know. Diancecht also exists to sustain your team (and maybe even for Afro if need be) potentially harder than Sol given this setup.
Water... a bit on the underwhelming side. You'll pretty much be running Shiva AW + Cthulhu AW + Vohu + Lakshimi all the time. And considering how late the good water girls come... it's not a good time to be a water main. Maybe fit in Pussy AW as well somewhere in the team.
Dark is kinda like the meme of DMM now. The best way I can describe dark teams... they're no more than the sum of their abilities. Just use whatever has the best combo of abilities lul.
And that's a really rough breakdown of the hime setups you can go with teams other than light. There are options outside of debuffs.
Oh, and I wanted to move this to general because this is becoming more a discussion than a thread for recommending mtixes. Uh... reply wherever and I'll answer wherever.
