did you not read my post. The planet in no way stated that it puts a force user on a siddious level which is what a sith HAS to be in order to be a threat to mace.
my point of reference for mace's abilities is that he beat siddious.
even nick gillard said that mace was a level 9 swordsman who is up there with yoda and siddious.
nobody knows what the heck levels revan or malak were because it VARIES FROM GAMEPLAY. again, revan could just be a good grenador and a mediocre swordsman.
ok so its stated that malachor boosts a darksider. how? a physical strength boost? a morale boost? a white blood cell boost?
the story says revan is powerful. big deal.
terms like {powerful, immense, unstopable, magnificent} are all relative.
asajj ventress was powerful, was he on her level?
padawan anakin was poweful, is he on his level?
we dont know enough about him.
also, with malachor/starforge whatever.......
if as a sith im of asajj quality, does it's boost raise me to dooku quality or if im a bane does it raise me to a kun or a siddious.
we dont know. what we also dont know is if the dark side boost deals in powers of persuasion, battle meditation, what?
the boost is too unknown to quantify.
but we have seen mace beat the emporor on the big screen so we know at least in terms of swords that he is above the sith as of ROTS.
