Hello. These are the builds I use with my fairly new character 
Gwen (the usual)
OQlkAkC8gZezO+EkDmemuhQGAnC
Ogden (or) Dunkoro (UA is very helpful when anyone dies)
OwUjMgPKEPMkLSXsecXbJZglP
Vekk (yes, 1 Searing Flames is not so good, this is just for nostalgia. Feel free to swap to Lightning)
OgljowMpZO74dBdbsiMoF4iaM
Olias (a good mix of offense and defense)
OAhjYghqIPXzyJGrqKNncDzLG
Xandra (also a mix of offense and defense)
Hayda (she is just here to look pretty and shout "Fall back!")
OQWlIwDbZYaoyIDuA5AcqpLD0y2x
Livia (the usual)
OANjUwG4jSyBUB4BKgbhVVaR3V
And, my own build (enjoying a Monk at the moment, still exploiting AP as usual)
Owcj4oe8HSLQ7i2kxkKiWfRQsN
I did have to progress / finish EotN for Livia, Hayda, and some PVE skills
early on, I used a generic Any/Me build with MOX, Kahmu, Tahlkora, or even Koss

Most playthrough seemed easy. Hope you find these useful.
