The Influence of Levels on Actions and Cross Class Skills

[Dreadnought]

"As mentioned under 1. Class-specific Actions, upper tier actions will be abolished in favor of scaling the potency of the base action according to level. The effectiveness and MP cost of the action will be dependent upon the level of your current class."

I have one very important question:

Does this mean that if I am a rank 50 LNC using Concussive Blow from my only R16 PGL that the effectiveness would be that of a rank 50? Or that of a R16 PGL?

Anyone have any thoughts on this?

edit
i see what you mean, yeah i wonder that too.
according to the english language, it sounds that way!
