Man i just don't understand how the AR def scoring works. Got a full win (all 5 attacker defeated) yesterday and then a loss couple of hours after that. Both, the win and the loss were well outside that 20 hour timeframe after losing Lift from monday, yet i didn't get any Lift loss for the full defeat yesterday. Maybe IS should lock the mode for a week and have QA take another good look into it.
On a different note, i finally got one of those reduced Lift loss defeats on monday, my team defeated 2 attackers (of 5) going by the replay and i "just" lost 60 Lift. Still no explanation why this never happened before, no matter how many attacker my team defeated.
Only thing i could think about without knowing any details about how the server communication works for AR is that there might be some sort of delay happen between app <-> server communication that has such situations happen.
I used a bit over 200 orbs and got a +def/-spd Winter Fae. 200 orbs for just one 5 star seems a bit steep for me but looking at the bright side, the IV's are good at least.
Her whole kit is designed to be a physical and magical tank, i'd say this is the best IV set, outside of the superbane in Spd (thanks for telling me Shaymin, didn't notice before).
Since you can refine her breath weapon, why not go for a Def refinement? With that your Elfae would have 50 HP / 49 Atk (with weapon) / 22 Spd / 40 Def / 41 Res ... and that is without merges, buffs, or any other bonuses to stats!
Cuddle her up, like the default skills imply you should, and you get at most +6 Def/Res from her weapon with 3 allies around her, and +5 Def/Res from her bond skill. That's 51 Def / 52 Res still unmerged and unbuffed from the outside.
And now think of her in an armor team with 3 Ward Armor skills, additional +12 Def/Res in combat, reaching up to 63 Def / 64 Res ... again, unmerged and without any bonuses applied from Arena bonus/elemental blessing bonus/Summoner Support. She could also apply a visible self-buff on her with a Wave skill ... and for her middling Atk stat, the game just gave you the perfect seal, Fierce Stance. ^^
You can push the festivitive chicken to insane defensive heights ... i'd almost say that Wary Fighter will be much more annoying on her than Vengeful Fighter. ^^
