Now that I'm thinking about it, I'm inclined to agree, but I still feel like there should be some kind of option for this at Chuunin. Suggestions?
I've toyed with the idea of making these all barriers/shields of some kind, but I really don't like the restrictions those would impose (especially standing still, with 100% hit chance, and for no direct damage mitigation, etc. -- it's all dumped into the bloodline effect) and it doesn't really "shield" anyone from anything, damage-wise. The only real thing it does is grant the user's allies the ability to force AoE as a counterplay -- by using AoE on them first. Which, as you say, isn't too terrible, is it?
Other than that, fixed. Also, dropped the Sennin one to twice instead of thrice.
