There was a change, that I didn't see in the patch notes, regarding the lower bound of the Melee Combo Duration stat for melee weapons. This change caps Combo Duration penalties to 0.1 seconds, rather than allowing Combo Duration to reach zero seconds. I suspect this change was made to prevent more "infinite 12x Heavy spam" builds from popping up, which I think is a fine way to attempt to squash those bugs into the future. That said, a side effect, maybe unintended, of this change is that Warframes with Exalted weapons can no longer benefit from using Melee Guidance to build Combo with a melee weapon that has Combo Duration modded onto it to make holding combo easier. This interaction allows Baruuk and Excalibur to more easily keep up their Combo, but this undocumented change breaks the interaction if you hit an enemy with the Exalted Melee itself rather than with just the waves from them. This interaction was really the only use case for Melee Guidance, besides the aforementioned "infinite 12x Heavy spam" setups, and it's a real shame to see it gone.
My simple suggestion is to remove the 0.1 second minimum Combo Duration stat from Exalted Weapons.
