Some things I noticed: I think that's all.
 * His explosive horn thrust gets replaced by a slime puddle attack when not enraged. The length of the attack has been shortened as well
 * His fists "dry" much faster
 * Same with his rage mode, it doesn't last as long
 * His armor is Rare 3
 * It looks like his weapons have been nerfed as well. The guy showed a lance, which I think it had 140 slime, while the regular Dios Stinger in 3U has 200.
 * As soon as you don't get hit by its fists when he does the jump attack, it won't cause slimeblight.
 * He doesn't spam his punch attack when enraged, unlike before.
