Sure, however the fact that the option isn't there makes the skill, more often then not, go completely unused in pugs. Of course there will be people who waste their goad when the see a MNK with 50% TP and the trash pack is almost dead...however as of now the only viable options are:
1. Keep tabs on what skills the other party members are using, use goad when you think they might need it.
2. Have them type out in chat, during the middle of a fight, that they need goad.
Neither of those are even close to acceptable. I'd much rather be able to make an informed decision by seeing their current TP, rather than for them to stop what they are doing and type it out. I don't want a BRD to stop his AOE just to tell me he needs TP so he can AOE, I want to see it for myself and allow him to AOE without stopping.
