GP sig

it says her combo meter reduces defencive stuff, yet with combo of 70-90 I still triggered regen on debuff vs sabertooth in new trial, wich was very unexpected for me, as I belive someone on forum said she needs combo of 50 to shut down anything. so was it a bug? or do I need to have her at sig 200? no clear description for that part of her sig in game. simply astonishing
