These have recently been released but I haven't seen a thread on it yet.  Some look very interesting, and even more interesting the legendary as far as I'm concerned:

Scabrius - Skinwalkers (Magic/Attack)

A1 - Gutter Knife - Single target, 50% chance (booked to 70%) of placing a 5% poison for 2 turns 

A2 - Gnawing Horde - AOE, 75% chance (booked to 100%) of placing a Leech for 2 turns.  4 CD (booked to 3)

A3 - Vicious Spite - Single target, 75% chance (booked to 100%) of placing a 25% weaken for 2 turns.  Also places a 50% increase attack on this champion if weaken is placed.  5 CD (booked to 4)

Passive - Verminous - Damage increased by 20% when attacking enemies under Poison debuff

Thoughts - Doesn't particularly interest me.  Could be useful on CB if someone pulls him early as he brings poison, leech and weaken to the table, but I will probably not aim for him

Duhr the Hungerer - Demonspawn (Spirit/Support)

A1 - Odious Bulk - Single target, 30% chance (booked to 40%) of placing Stun for 1 turn

A2 - Cannibal Litany - Places a 30% reflect damage on all allies for 2 turns, 15% continuous heal on all allies for 1 turn, and heals all allies by 15% of their max HP.  5 CD (booked to 3)

A3 - Hungry for More - Revives 2 random allies with 50% HP, then fills their turn meters by 50%.  6 CD (booked to 4)

Thoughts - From what I can gather, Demonspawn only have 1 champion at the moment that has the revive skill, which is Duchess.  This brings a much needed gap to the Demonspawn faction wars, and one that I will likely aim for over the legendary fusion.

Thylessia - Knights Revenant (Force/Attack)

A1 - Weft of Madness - Single target, 50% chance (booked to 70%) of applying Debuff Spread for 1 debuff to all enemies under Hex

A2 - Shrieking Voices - AOE, increases duration of all debuffs on all enemies by 1 turn.  3 CD

A3 - Melancholia - AOE, places a 60% decrease DEF for 2 turns.  4 CD (booked to 3)

Passive - Feast of Woe - When attacking enemies under Decrease Defense debuff, has a 50% chance of placing a Hex for 2 turns

Thoughts - I assume this is part of the puzzle that Plarium is justifying for the Cleo changes to the daily logins.  She has an interesting kit that synergizes well (Open with A3, passive kicks off some Hex's, then A2 to increase all debuffs) but I probably won't aim for her specifically.  AOE decrease defense is always useful in Faction wars though.

Demytha - Dwarves (Void/Support)

A1 - Fires of Old - Single target, 2 hits, places a shield buff for 2 turns equal to 10% of this champions HP on the ally with the lowest HP

A2 - Light of the Deep - Increases the duration of all ally buffs by 1 turn, and decreases the duration of all ally debuffs by 1 turn.  Also heals all allies by 2.5% of their max HP.  Heals a further 2.5% max HP for each turn added to or removed from the duration of buffs and debuffs.  4 CD (booked to 3)

A3 - Channel the Bloodline - Places a Block damage buff on all allies for 1 turn, as well as a 15% continual heal buff on all allies for 2 turns.  5 CD (books to 3)

Aura - Increases Ally Defense in all battles by 20%

Thoughts - This to me appears to be a godly champion, unless I am missing something dramatic.  Part of me thinks this might be nerfed at some point, but a 3 turn block damage on all allies that goes from 1 turn to 2 turns with the A2 is incrediable.  

For a speed tuned CB team I think she could create a budget unkillable all by herself.  Open with A3 for the first AOE attack, then A2 for the second AOE, then A1 during the stun (making sure she isn't the target).  Rinse and repeat.  If you bring in a second AOE block damage like Warcaster then you can probably have a full block damage team up and running.  

100% aiming for this champion over the legendary, and I feel like I must be missing something (which I hope someone will tell me).
