Tiberian 40 - Request to Developers to Reduce Malus

Players are commenting that it seems easier/faster to dig suddenly, and that the devs lowered malus from +4 to +6. Even though a base may say there is 60% malus, etc., your army will get through the defense much easier. Or at least, this is the perception.

Could we get confirmation that malus was indeed lowered (even if the notifications have not been changed)?

And if so, thanks!
