Yup. And worth giving the new toys a try.
2.5 Elincia
3.0 Yuna (Multitarget)
2.0 Arnaud
2.0 Stocke
1.5 Eiko
Elincia ubers Yuna & Arnaud's evade with Authority and is a dangerous ST threat, especially since Arnaud can toss Slow Down on speedy targets so that they eat 4x Amiti. MT sealstone makes Yuna a solid MT healer and MT buffer; FFX Protect / Shell are pretty good already so merely a 34% drop in damage is still totally useful vs. magic or ITE physicals. This is the core of the team.
Stocke is a tanky extra reviver (with a dash of evade thanks to Elincia) who can also switch in the right person for a job; e.g. 2x Arnaud Sleep attempts, 2x MT Holies, 2x Elincia beatdowns on a tanky boss that can't be allowed to live. Should give the team extra flexibility. For the final slot, the most Elincia themed person would be Marisa, but this team already is worried about ITE physicals and that would be even more ST when the team needs more MT options, so Eiko it is. On one hand, it gives physical attackers something useful to do rather than ramming into super-evade or Stocke's tankiness, but you know, if Eiko is enough of a threat to require takedown, that's fine by me, they've got 2 other revivers to work through in that case. More importantly, Eiko offers some more MT damage options, and much earlier than Yuna's F6 Holy. Sometimes you just need MT to work a group down and threaten 'em, and she does that, along with provide more MT revival, healing, Esuna, dispel, elemental nulling nonsense, etc. Icing on the cake is that when facing enemy mages with physical backup, Yuna can drop MT Reflect and Eiko does not care at all thanks to Reflect Null allowing her to still spam MT healing all day.
I think the team has some amusing combos & synergy, if lacking some raw kill-or-status-them-right-away power. In other words, they get a fun & exciting ride.
