So far I've had three times over the past two weeks that Invigorate has not given me any TP. I'm just fishing around to see if other DRGs (or MNKs) have noticed this happening at all?
If so then I plan on putting together the information that is needed to report an in game bug, if I'm the only one then maybe I'm just missing something about fights having a TP drain or... I don't know maybe I'm just an uber noob. Who knows.
