Is there a gaping whole in my team I'm not seeing? I figured maybe a finisher would be good, but since dual Orlandeau is the way to go until Agrias 6* I can't opt for a friend finisher.
It's probably better to think of your pool of units rather than a specific 5-character team, since who you take in will depend on the situation:
Debuffers aren't very useful if the target resists break
Elemental buffs (from Minfillia/Marie) are only useful in element-based trials (e.g. ifrit/siren)
Chainers are almost always useful, but some trials demand sustainability over damage, especially if you have a team size restriction. You may only be able to bring in one damage-dealer.
Noctis is weird since he's a backup "everything" (can buff/debuff, resurrect, HP/MP regen, evade tank, and DPS) except chaining.
Who goes into a team depends a lot on the situation especially for trials, for example Cecil is a fine tank most of the time, but sometimes Snow is better since he counters a lot more frequently and attracts attacks rather than covering others. WoL will be another reasonable option if/when he gets his 6* (and of course Wilhelm/WK Noel also exist for those who have them).
I would like either Ramza or Marie from my pull, but I don't expect to get either. I think as long as I don't get Lightning, Luneth or Queen I'll be pleased, and TBH I'm pretty happy with my team as is.
