Changes to NIN are amazing, such as increased potency and lower TP on weaponskills, reduced CD for Dream within a Dream, passive 20% increase with Dripping Blades II, etc. However, I have to agree with the above posts in regards to Ten-Chi-Jin. The recasts take just way too long. Feels like there is a 1 to 2 second lag between execution of each ninjustsu when using Ten-Chi-Jin, when there should be 0.1 - 0.5 sec. Yes, you have to be immobile when using Ten-Chi-Jin, but that's a trade-off due to double potency on all nunjutsus used. Other than that, it's a great ability.
