Well here I am a few days after asking about B3. I've improved a lot with the character and to add to the B3 into Tele discussion I'd like to say that although the opponent has no reason to be standing from mid range they have a lot of reasons to get in my range trying to hit me either via some advancing string or jump ins and B3 into Tele works pretty much like Kabal's B12. Of course B12 is a much better move for a billion reasons but as a Kabal player myself I kinda get the same feeling. I also use it to punish Sub Zero's Slide into full combo, I haven't got the time to see if it's real on practice but it worked online.
Since Im already here I'd like to ask another question. How do you guys feel about practicing that combo that was popularized by Ketchup (I guess?) which is basically 113 into tele, 113 (whiffing the first 1) into B1,1+3 or into another 113 into BF2?
I've been debating whether I should put time into learning it because it seems super hard and I've seen even players at tournaments dropping it and leaving at least 300 damage on the "field".
