So where is the dictionary, becuase some of these could have various definitions. For example, the whole KG-KT thing is a little confusing (you can have 2 KG if no KT is chosen, but you can have 1 KT and 1 KG if one is chosen? O_o).
Secondly, juinjutsu and fuinjutsu go hand in hand. You can't master juinjutsu without knowing fuinjutsu, as juinjutsu is based off of fuinjutsu. Curse "seals" require the knowledge of "sealing" one's will and all that good stuff.
Thirdly, genjutsu vs taijutsu will probably lead to further death of genjutsu. Cause seriously, if it comes down to moving faster and hitting harder against using an illusion some guy will cancel with the batting of an eye, then I think taijutsu would be the obvious choice... (unless you get creative with genjutsu usage...)
The inability to master implant is absolutely ridiculous. Just count it as one of the KG or whatever and it'll be just fine. That'll make getting an implant less of a loophole, and people won't get another implant just to get around the KG-KT rule or the elemental affinity restrictions.
What is considered "signature" ninjutsu? I have alot of ninjutsu, though just the budging of my shadow kind of gets people on edge sometimes. xD
Unless you start getting number values for these things, you are not going to be able to judge the difference between someone really good at chakra and someone who has alot of chakra (sage mode I guess being the exception... but then there is still gray area...)
If you are going to make restrictions like this, once and for all, publicly eliminate the 'have it in-game, have it in RP' philosophy, meaning if we have restrictions on what our in-game stuff can give us in the first place, then why bother linking the two together in the first place?
And when you refer to '1 hiden (dunno where you get hijutsu from...)', I hope you mean sets within those secret traditions, because I still have a large arsenal of Nara techniques, both custom and canonical. Some are a little overpowered compared to what the Nara in the series do, but I don't see the Yamanaka running around taking over people's minds and reversing Koto... Oh wait...
So, aside from me being slightly dueche', I can't help but note that making something like this might be hard to implement in actual practice. Maybe not superbly hard as I'm sure plenty are sick of the OPness, but some of these do clash. For example, Rinnegan resets only allowing for the mastery of one elemental affinity directly clashes with one of the powers so granted by the dojutsu itself.
Regarding Jashinist Immortality and Earth Grudge. I personally do not believe they are gode mode; Bocc was exceptional in its usage and that rubbed some sandpaper over skin. But in the later stages, Bocc used more Rinnegan-Uchiha than his jashinist curse technique. His inability to die was a nuisance, but he could still be sealed, chopped to pieces, soul robbed, etc. Earth Grudge could just have a max heart limit, though what that would entail is subject of debate.
