The setting of the number of combos is wrong

[wolfe2568]

Now the warframe's combo count is set with 100%. For example, the combo count is 100%. I have a card that reduces the chance of combos by 90%, and a card that increases the combo by 70%. Calculate it, 100%➖90%➕70%=17%. Does it look something wrong? In fact, there is nothing wrong. It is equal to 17% instead of = 80%. I think it is a wrong way to calculate the number of combos by 100%. This is not rigorous and should be changed to 1. If the set value of the combo count is 1, then 1➖0.9➕0.7=0.8 is the correct value. So I think the official should modify the setting of 100% combo! ! !
