Bison remains essentially the same and serves the same roll as he did pre-patch. He is a footsie, frame trap, and tic throw monster. This character has suffered no stealth nerfs and benefits most from system change removing red life off of grabs. Bison was already blessed with good walk speed, and good normals yielding acceptable frame advantage- and with the new frame trap options he gained- he is even more so a threat when he is upclose in the opponent’s face.
Bison gained different block strings with the stand medium punch buff to make him less prone to raw launchers. Before, he would have to do low short, stand short, medium kick. Now you have the option of doing low short, stand short, stand strong xx special.
Bison received a nerf to his teleport. Added recovery frames means you will now have to commit to using it in many more instances. However, it is still unpunishable in certain situations such as auto correcting warps that get you out of the corner safely.
Bison received more pushback on light scissor kick. This is not a big change, as it was already -2 on block.
