He may kill you off in 3 to 4 hits, has a few decent buttons in neutral, carries an i12, a good Soul Charge, push you back out with some of his moves with good range, grab break LH, and has a good RO game but so many others can do those things and yet are pulling these off much better and more consistently than him atm. Zasalamel has a much better mixup game into RRO than Astaroth does and unlike Asta, has better tracking into it. Amy’s grapple break LH currently deals more damage than Asta’s. Ivy and Mina have superior options for keeping out and than Asta does and unlike Astaroth, have superior movement compared to him. Voldo, Groh, Raphael Mitsu all have better buttons than Asta in a neutral game. NM, Sieg, Cervy, Sophitia and Hilde have just as much reward as Asta on a whiff punish yet take slightly less risk than him (maybe except NM) and much the zoners they also have superior movement over him, and Cassandra is much better at playing rushdown than Astaroth is. Asta may have tools for the situations he’s in but he’s not at all reliable for these things. His armor is utter trash too, and his matchups are some of the worst in the game.
Then again, none of those characters (with the exception of Ivy with her semiblender) has the blender.
Astaroth is all about the YOMI, the blender and his good frame data and pushblock on Bullrush and longer ranged attacks.
That’s why he’s constantly labeled as a walking diceroll.
How is this not a good thing? That is what made Mitsurugi's past incarnations with his cheap grounding 2KB a huge issue in the past.
Astaroth has the same but with throws and his terrain control meaning you can't go YOLO aggro against him and you don't have much margin for error as he HITS HARD and ROs out if you ain't aware.
I agree with you that right now he was nerfed but he IMHO is still Top 10 instead of Top 5 ATM but is still early.
