To break the habits that are hampering your gameplay, you have to openly acknowledge them first.
One method that helps is to study your replays and see what the opponent is blowing up, but personally I find it more effective to lecture yourself mid-match when you get punished for doing the same tactic twice, maybe three times, without changing it up. Auto-pilot tactics only work against players who have yet to learn of adaptation, and then that all crumbles when you face someone with a significantly greater degree of competence.
Subject yourself to various environments of gameplay every time you hit the training mode. It's always welcome to review your answers to familiar scenarios, but remember to branch into unfamiliar territory. And with how the variation system works, as well as KP2's new characters and balance changes coming up, there's still quite a lot of exploration ahead of us.
