Well on Goad the way I see it, it can only be cast on others, makes no sense to Goad yourself anyway, and you have Invigorate regardless. Goad is like utility stuff, kinda like Apocastasis, Mantra and such. Can Goad tanks for TP which is gonna be great, and Wars can debuff slash for you, that love story.
The 10% raid wide has poor uptime(you need Hide to cast it, which apparently Suiton can also provide but since you also need to Huton yourself and Ninjutsu most likely has 20-30secs cd, while Trick attack has 10secs duration, it's not that much uptime), though is still kinda nice especially for a burn phase.
Poison still puts the damage buff lower than GL3 monks. Monks is 15%speed and 27%dmg, 32% with the 5% from Fists of Fire, Nin is 15%speed 20%dmg, so kinda need to see how the rest compare. The potency on Ninja stuff is a ton higher though, so don't know how it adds up.
