"Someone" is notorious for downplaying his character, I am not surprised, look what he did to mk9 kabal, downplaying so much that the character had gone to mk9 history as the most OP character lol. He is trying his best to downplay Erron in this game.
input window set as long for me, i get it pretty consistently. make sure to dash cancel the norma i.e. input the normal as fast as you can after erc cancel., it comes out a tad faster.
BTW you can convert off of a bf1 amplify in the ring master variation. In the corner you can do b3u4 bf1 amplify dash cancel forward 134 bf2 does 317 damage.
don't do 33 string, do 3 as a single hit, so the most optimal i've found in corner is: b123, standing3 (not 33), standing 3, standing 3, 333db2 amplified, 333d4. Damage: 439
