I am a little confused on the definition of "sub-power." It seems that back when only Vacuum (and maybe Heat or Silence) were considered sub-powers, the general consensus was that sub-powers were things that you could manipulate by using your power over an element that are not the same thing as your element. For example, you could use Air to make a vacuum, but Air =/= Vacuum. Just like how you could use Fire to control heat, but obviously Fire and Heat are not the same thing. Basically, sub-powers gave you a wider scope of abilities that expanded outside of your elemental powers, in a way.
Now, we have sub-powers listed on BS01 such as Cyclone, Hypnotism, Telekinesis, and Telepathy. The description above says that "Several powers exist that involve manipulating only a certain portion of an Elemental Power." But does this really make sense? Cyclone is basically the same power as Air, only a more limited version at that. Same goes for Hypnotism, Telekinesis, and Telepathy. Psionics is by definition (as I recall reading it back then) the very ability to use things like telekinesis and telepathy. So should these things really be considered "sub-powers?" If there was a being (or a mask power) somewhere in the MU that could make a giant hand of fire (and that's literally all he could do. He couldn't manipulate normal fire like a Toa could), should "Hand of Fire" be considered a sub-power? It just doesn't seem right.
Speaking of Vacuum, should it even be considered a sub-power of Air? According to BS01, Vacuum is the power to absorb specifically air, but apparently from what I've heard, Lehvak-Kal could create vacuums by absorbing other materials (such as earth or water) too.
