I thought about that as well, and no. As I said, burst is the nuclear option, it would be able to be used during lockout or even when counter broken, there's also much less guess work for burst (will he attack or will they block versus will they do 1 of X moves or will they counter break), so there is always a reason to burst, at the cost of meter of course. Besides, DI arguably works as a combo breaker as well (combos can just fail because of DI) so there is already 2 combo breakers in game as is. That being said, if this were to be added burst meter gain MIGHT need to get nerfed.
The purpose of this is something to replace DI, if that means 2 direct combo breakers rather than one combo breaker and a pseudo combo breaker that makes combos feel weird (unless your on the ground), I personally would prefer the former.
EDIT: Or, yeah, remove burst. Would be a big change, but that too is an option.
