At last!!!! After I got 2 athena Victoria and 1 hera victoria, eventually i got Zeus victoria

SO the million dollar question, what should i do with this zeus victoria? CK, BK, Paladin, HD?
One of the athena victoria already became Holy Defender, another Athena Victoria is on Zealot path.
My current member team both pve/pvp
1. *5 Zeus Shizu Magebane
2. *5 Athena Kai Ninjaaa
3. *5 Hera Zedd Mind Warder
4. *5 Hercules Cybella Grand Ranger (will be replaced with the ares one, just got it recently)
5. *5 Athena VIctoria Holy Defender
Bench:
1. *4 Athena Teressa priest -> i believe will go to inquisitor
2. *4 Athena Victoria Zealot -> will be LB if my zeus victoria take BK path
3. *3 Zeus Victoria Knight -> I want to kiss you

Sadly, i don't have any *5 potential Champion, only Lancer fiona for gold event

PVP wise
I already have Ninja kai, so the swapping job will be him
PVE wise
I'm still chapter 2 Legendary, i don't know if my Athena Victoria Holy Defender strong enough mitigate the damage for next stage
My Choice:
BK : Seems a good choice, good attack and def
CK : Is my hercules Kai ninja good enough? If not, i need to reconsider this path
HD : Is my athena victoria HD will do any good for later stage? Or the BK can do the main tank?
Paladin : I read somewhere that paladin need Royal huntsman to be efffective, i don;t have one, so nope
Can you guys help me? Thank youuu
