Dante said in OOC that he's concerned about fights being over hella quick and people not having any defence, being locked into certain builds, etc.
My suggestion is that handsign statistic be deleted and merged into Ninjutsu, and to divorce max chakra from Ninjutsu, instead making "Chakra" its own stat.
Have the derived statistics of Tai.Def and Nin.Def run off of Stamina and Chakra
Have Stamina influence max health tai.def greatly and nin.def lowly, and chakra influences max chakra, nin.def highly, tai.def lowly.
I'm willing to refine that idea, but I feel like having that choice would do a lot to differentiate people's builds and focuses.
