Fuinjutsu won't be discouraged, however it is something that will be, like Genjutsu, Ninjutsu, Taijutsu, etc., its own thing, and so it will be extremely slow to work with unless a character goes full-blown support mode from the get-go. (Not to say going full-blown support wouldn't be amazing to see someone try out. Bonus points for creativity in your support methods ^^)
Hmm Hmm! I'll have to come up with something interesting then!
