Wow, you are extremely lucky with your Kiera's
Here are my recommendations:
- Kiera's - Go for one elementalist and either you limit break her or go for either Mindwarder or Rune Magus(right now in the current PVP meta, she seem to fare very well)
- Zedd with zeus is very weak, so bench him for now and reserve for limit breaking a better faith one
- Kai - Magebane is very good in PVP
- Victoria - go for blood knight, especially good in PVE and decent in PVP
- Vincents - go for Berserker(Ares) if you fancy more damage or go for Gladiator if you fancy crowd control for PVP
- Theresa - Inquisitor and Archbishop are almost equal, it boils down to preference. Inquisitor for consistent healing and Archbishop for on-demand but somewhat RNG based healing. Their active skill's healing throughput is almost the same but Archbishop's heal shield seems better in PVP and with the current event dungeon
- Luthor - Keep as fodder for better faith, but right now Luthor's are relatively underpowered compared to Theresa and Lucille
Same, but you can also Rune Magus for your zeus Zed for a more offtank utility support, since that is the role of rune magus(more for pvp)
And I would go against a Berserker Vincent tho, unless you have very good heals/shields set up for him, it would be suicide
