I know the fact that you can push the power - yet, there are too many powers with a Power requirement that makes them inusable since most characters do not have too may HP.
Also, there is an obvious misstype problem with the P-requirements of almost all the powers I listed, as versions that are supposedly more powerful hace LESS requirements.
Example: Jamming is listed as having a P15 requirement for its standard application (Medium range), but if you do it as a more powerful version (Long range) the requirement listed is only P12!!!
Looking at other powers with different range options, I see that augmenting a power increases its P-Requirement usually by +2, so it seems that the true P-requirement of the power should be 10, not 15.
From a setting balance point of view, think about how much useful a Jamming ability is in the universe; P15 is an awfully high requirement, one that no telepath of any race can reach (not counting broken individuals and vorlons). It should be a defensive ability commonly used, but listing it with such high P requirement makes it scarcely used; the power simply is not useful enough to risk sacrificing HP to use it as a P15 power. From a setting point of view, it just means probably nobody will ever use it except in rare ocassions.
From a mechanic balance point of view, Jamming is quite obvious for any Telepath entering a jammed zone, and is mainly used to disable opponent telepaths by increasing their telepathy checks on using powers. This means that if two parties with telepaths are opposing each other, whoever wins initiavite cound potentially disable the other team's telepath.... but in doing so he himself is unable to do other powers, so it's no real vantage unless one of the telepaths is much more po werful than the other. Any way, as there are not unbalancing consecuences, lowering the power P requirement to 10 should be ok.
If you add all these observations, as I did, it seems pretty obvious to me that there is a misstype with the P-Requirement of the power (Jamming in this example), and it should be probably P10. This same observations can be made for all powers that show inconsistency either in the more powerful versions, in the game mechanic balance, and in the setting itself.
This is why I posted asking if anyone has ever done a more careful revision of the powers, since there are many obviously with errors of this nature.
