Theres a lot of killy in Titania. Though shes probably more a 'tank' crew in Neverborn.
Whole crew is undead (besides Waldgeists and Bultungin), so they get h2w. In addition armour +1 is common. And Titania can reduce severe dmg flips to moderate within 4". Pretty nice.
Offensively, Rougarou, KJ and Titania herself are pretty nasty. Rougarou and Titania are a little deceiving, being min 2, but have excellent triggers on Crows to not only add +1 damage to an enemy model within (i think) 2" of an underbrush marker, but also place that model in contact with said underbrush marker, making it a control trigger as well. Whilst KJ has Onslaught on min 3, making him simply brutal.
Her mid tier minions, the Autumn Knights are pretty strong, armour, h2w, df6 and a trigger to deal 2/3/4 in return to an enemy attacking them, plus they can force an enemy model to attack them or discard a card. Not bhed.
I think Aeslin (Titanias Hench) is very niche. Mostly for schemes like Dig their Graves, as she has ranged attacks that can drop scheme markers, but also can deal out some blasting injured, which isnt horrible.
I think where some really obscene tech comes in for this crew, is when you throw in something like the Hooded Rider. He doesnt get anything directly, beyond what the crew already provides, but The Gorar, Titanias Totem, should the Hooded die, can resummon him, or even better, Changelings can copy the Gorars 'Mold of the Other', tactical action, to resummon your Rougarous or mid tier beaters. Adding a heavy layer of toughness to the crew.
