I personally don't have it on my bars and don't see the point. Outside of someone coming back from a disconnect in the middle of a fight I've never been in a situation where it would actually benefit anyone. But then I'm rarely paired with another melee and I've yet to witness a tank burn his TP before we could kill a trash pack. And if you manage to run out of TP on a boss fight...

I would say if someone is bottoming out without Goad they either need to work on managing their TP better or their group needs to stop sandbagging and kill mobs faster.
