The thing we have to think about here is the overall * for buck when it comes to spending seal scrolls. Spending on Sage is like a really high risk high reward type of thing in that if you don't get him you practically just wasted your scrolls. I don't like that type of thing so I wouldn't rec it, but it's all about preference here.

If you spend in something like either Jinchuriki or 5 Kage, you at least have a chance to get solid characters like Mabui, GNW Tenten, et cetera from the commons. In Sage, all your commons are easier-to-obtain characters like Jugo...
