Inconsistencies between activation times and root durations

[Pzn]

I've noticed several powers in the game have either incorrectly labelled activation times or bugged animations.  I'm not sure which way they were intended to function.  Dark regeneration, for example, is listed with a cast time of 1.17s but takes approximately 3 before you can move or activate another power.  Another example is neutron bomb, which is labelled with a 1.67 activation time but again takes nearly 3 seconds to complete.  The animations on these powers seem to match the labelled activation time but there is a strange delay before and after that causes the powers to be functionally slower.

Are these powers that have alternate animations? It's a known bug that some of the alternate animations lock you down for about twice as long as the animation time should be.
