The real issue here is that the OP for this thread is negative. The thread could have been "NIN, please think about WAR TP when using Goad!" and the message would be out there that NIN should try to be aware of and consider the Tank's TP when going to utilize Goad.

That said...

Goad is not quite like paeon, in that there is a level of decision-making because it is a single-target ability and it has a long cooldown. DPS run low on TP easily during AoE fests, so sometimes it's a good idea to hit them with it (MNKS benefit greatly from it on long boss fights, too) -- I could see many NIN thinking along these lines, as most of them likely came from a DPS background and know the issues better for DPS, whereas WAR seemingly never truly needs a BRD to cast a TP song.
