Honestly, it's not the specific test that bothers me, it's rather the nature of tests. You can take all the Litmus Tests you want, but really the only way to tell if your character is original and well thought out is by reading your stuff. These things do provide a good benchmark though.
As for the "dying and coming back to life thing"...well, I admit it's been overused, especially in the BZRPG.
I started playing in the Academy in October of 2006. Back then, Yuki would have probably passed the test with flying colors. She was a normal Academy toa with powers below average and a plain staff for a weapon. The only extraordinary thing about her was that she was a good crystal carver and she was actually a spy for a matoran organization. But as things went on, she sort of developed in response to other people, and well...it got complicated. She only go her speshul powers quite recently, but that's a story for another day. And she's a samurai, not a ninja XP.
I'm pretty sure most of my other characters could get by this test, though.
