In their most recent Textual Stream, Iron Galaxy have asked Killer Instinct fans to fill out a new balance survey, to help aid their future patches and changes to KI. This survey mainly focuses around combo breaking, with Iron Galaxy asking questions about whether combo breaking is too easy, whether the potential damage cleared by combo breaking is too much or too little and gauging how both attackers and defenders feel when they combo break.
One of the main complaints about Season 3 is the strength of guess breaking compared to actually reading your opponent’s moves and breaking correctly, so it seems Iron Galaxy is attempting to redress the balance by potentially making guess breaking less of a viable option.
In addition to this survey, the Textual Stream did hint that some big Killer Instinct related stuff is being revealed in the not too distant future, with it happening after Halloween but before Thanksgiving. With another recent survey asking about potential new characters for Killer Instinct, this may be a hint at an upcoming Season 4 reveal. Make sure to read the whole stream, which also confirms that all input bugs which came with the Shadow Lords update should be fixed upon the release of the next patch.
