Especially since Faye has unique skills which scales with health, maybe Hercules faith would be good for her!?
Maybe Leah's Aura would be good for arena?
But that's my opinion.
Share your opinion on the new heroes down below

It also have 40% dmg reflect , The barrier , dmg absorbs and heals really helps my DD stays alive in arenaPaladin Faye could work well with mystic team with 20% MAG buff and damage absorb, heal trigger chance is a lot higher than Holy Defender (75%) but only 5% of HP.
Really good summary of the new heroes! Thanks for the insight, I didn't pay much attention to Leah at all until I saw your comment, maybe work towards her with Blood TokensHoly Defender Faye probably the most go-to for most people, mostly because buff removal and max hp buff but, heal trigger chance is too low to be reliable. (40%)
Paladin Faye could work well with mystic team with 20% MAG buff and damage absorb, heal trigger chance is a lot higher than Holy Defender (75%) but only 5% of HP.
Berserker Leah is ok I guess, her skill do AoE unlike other berserkers, not much to be say about aura, which is basically Freya with no stun but higher chance.
Warlord Leah is GOLD, she can push back whole line of enemy, aura can be work with other warrior classes very well.
Silvia is terrible, her skill do nothing but damage.
Does it work in story mode?If u have faye, i advice to not 5* it yet, at least if u plan to make it holy defender, don't..
For now.. we dont know the detailed about her skill yet.. the skill say it can remove all opponent bonus effect, and when the skill hit it Will give smoke effect with word 'remove buff'.
But when i try it at practice arena.. it cannot remove Lucille Shield, archbishop teresa Shield, gladiator vincent hp buff, +atk +mag from passive aura mind warder Zedd, sharpshooter cybella atk or crit buff i forgot.
I hope the moderator can give me / us explanation about this.
So before the mod give us info or another player that have holy defender give us more info its better for u to saved your faye at 4* or just advance it to paladin class.
I'm leaning towards Paladin Faye too, as she has the Party Reflect (not aoe/line).It also have 40% dmg reflect , The barrier , dmg absorbs and heals really helps my DD stays alive in arenaPaladin Faye could work well with mystic team with 20% MAG buff and damage absorb, heal trigger chance is a lot higher than Holy Defender (75%) but only 5% of HP.
