As you stated, this absolutely should be reflected in the help text for those abilities, and so I've just added it. These changes will go live in 1.19.

Thank you very much for the post!
I noticed this yesterday too, it'd be nice if we could gear a clearer explanation of what the additional TP does. I'm not entirely sure we any would want to use this over using 3 1000TP abilities -- Mine (Rank 14) averages 550 or so damage, where as I can do Skewer, Circle Slash, and Moonrise for 220+ damage each...
