Because Rivals 2 add grabbing, there will be shields (at 0:41, you can see Maypul using it), and so, parry too.
Depicts peoples asked to keep the Rivals of Aether DNA (very fast combats) and not add grab/shield, Dan's (the main dev/designer) thought it add more depth to the fight (and, I suspect, lower the bar of new players and Smash players because you could simply be destroyed in seconds if you were not prepared in original one). While it's sad to see a specificity of original game removed, I think he is right and this choice will push its IP further.
Ah, and of course, rollback netcode written from scratch. I mean, rollback netcode written from scratch on a second iteration of a beloved platform fighter.
Maypul is my main on Rivals of Aether and I'm in love with this one. I was not that much impressed with other characters (quite the opposite TBH). Yet the attention to the details, the augmented moveset and the poses of this Maypul are really impressive: She is fun to watch and looks fun to play.
It's hard to say just watching the moveset, but it looks like area of ground attacks is big. Combined with the speed (the Maypul signature) I have the impression she's really deadly. In original Rivals of Aether, Maypul is not a strong damaging character, but a very fast and hard to manage one.
The new multiple plants push her power further. Puppy seems to be the most technical and it will create some epic tournament moments, IMHO, and the edge one will make her off stage management more dynamic. In Rivals of Aether, its off stage is deadly, but at a particular angle.
I also realize she have a smoker badass almost quiet voice which is totally on par with the description (she protects the forest and talk to plants). It's so well made and integrated I actually not even notice it at first watch! Keep in mind indie fighting games often fail on this (voices can be… well… bad and repetitive).
It's a VS platform fighting game, it can't be balanced at launch before many patches. But it will be an instant buy for me.
