So in comparison to the other paths, jounin is slacking a bit in my opinion. Anbu is pretty much entirely utility based, and has movement, medical can heal, has a damaging move which also takes away chakra and ofc also has movement. They all have movement and besides that for jounin, it only has kunai barrage and teleport (another movement). I think to balance it out in terms of having a utily would be the addition of shoulder pills which would act like medical healing where it slows you for a bit but it would regenerate some chakra.
While I personally don’t like subs, I think its not a problem with utility, and more so the fact that they are so heavily under-utilized. I almost never see anyone use them at all and I think that just because no one uses them doesn’t mean they aren’t good.
I have to agree, I think 3 subs is way too many.. sub 1 and MAYBE 2 but 3 should be something else and then some utility like in my ex. The soilder pills but again anything but does not have to be fancy as Darth said.
I use substitutions 2 and 3, they have niche uses but I have talked about a Jounin revamp in the past. This isn’t something I’m going to work on now though, not really my biggest priority at the moment.
