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.
It also have 40% dmg reflect , The barrier , dmg absorbs and heals really helps my DD stays alive in arena
I'm leaning towards Paladin Faye too, as she has the Party Reflect (not aoe/line).
The strategy is:
Softer team - the reflect will act as kamikaze/ or vengeful spirit, on the side note, the Mag buff is very ideal for \soft\ mage & healers (high spell dmg and heal)
Tanker team - If you have a grand ranger (mis-direct) or 1 more tanker to Taunt-ALL, this also viable as they whole team will compensate the lower auto-attack damage with the reflector.
Well, maybe cause I already have Grand Ranger and Victoria Paladin, and no good mystic, I'm suggesting myself to Tanker team strategy. Kudos, thanks for reading anyway.
