I am a recently returned player. When I played last gnw treasure did not exist. I have pulled 100 times from the treasure so far only to realize that I have no idea what is good from the treasure. My question is what ninjas from gnw are good? Any sort of tier list of sort for specifically this treasure would be awesome, especially for the commons as that is what I have obtained the most of, but knowing which rares are good would be nice (first and only rare I've pulled is Mangetsu - he doesn't seem that good to me but I could very well be mistaken).
