Looking at the new update information from project moon, the base EGOs are having their costs changed to -10 Sanity, -15 for Hong Lu's land of Illusion, and -20 for Faust's Representation Emitter.
Representation Emitter now heals 10 Sanity for the lowest Sanity allies, i'm surprised they changed the base EGOs like this at all, but Faust's was a bit to strong as is.
Abno battles called Focused Battles now, so we might see Human Battles eventually phased out?
For MD2 Hard mode, the starting Cost is back to 200, and two star identities Cost 0 like the base Identities. Rest stops and shops now appear at fixed locations at the begining of floors or right before the final boss.
EGO gift spawn rate after a battle is determined by how much Cost you earned during the fight, and Lunar Memory has become to max rarity.
Starting with Rhino Merusault for the new identities: i'm surprised that Rhino Merusault is Bleed and Speed based like a Rabbit, but then again, the Rhino's were the most generic of the 4th pack mechanically, with them just being beefy tanks that dealt good damage.
He also lacks a way to apply Haste to himself(his only way of gaining speed is by his passive, which increases max speed), although his skill 1 and 2 do give him Charge, and his skill 1, while buffed by Charge, does not expend it. It's also a bit weird that while he applies Bleed Count, he doesn't have a way to increase it's potency.
His Skills also don't have Sloth, depriving him of his EGO, base and Gacha. That said, his Base EGO only needs 1 Sloth, and Envy/Gloom are better Sins for giving other charge IDs access to Charge EGOs.
Zwei Rodya is just shit, her Skills don't give her useful combination of sins, and both of her mechanics; Shield and Poise aren't good.
