Well, i did read the FAQ twice before doing post...
I'm reading the forum to see if i don't do any double-post anymore, @_@

Oh, now i get it...
Like Minato Yellow Flash?

If yes, i would love see it in-game :3

What you need to be an Environmental Artist?

Right now, by what i saw in the animations, if you click any number, it can do any kind of the 12 seals, to do the jutsu just click the right numbers and done!
I suggest that each number gets a seal, here goes a order(Just to explain)
0=Monkey  1=Dragon   2=Rat
3=Bird       4=Snake      5=Ox
6=Inu        7=Uma         8=Tora
9=Boar      /=Ram         *=Hare

There are 12 symbols, we can only have 10 with numbers, so... Let's add /* or any other key(If you want to) to be the last two.
It's going to be better in my opinion, and even some good people can see which jutsu they are doing(Yeah, try to be a badass), i don't know if you have any counter against it, if so, say so i can try make it better.

Here goes a good example of how it works... Suiryuudan no Jutsu, 44 Hand Seals:

50*29357386845/49/503157/8425032901357/8420*9152503293

I don't know if this is the right order, if i'm wrong correct me, but it's just an example anyway.
Just by doing this, i almost got all symbols and numbers decorated, but it's going to be fun, and you can try getting all jutsus in your mind and see what is your enemy up to =D.
Well, it's just a suggestion to make the game a bit more realistic to Naruto, that's what you guys want right? (Not mocking you, i'm talking for real I really like that part too!)

Edit 1:
I decided to get in-game and see the seals...
Chidori=398 so it's Bird, Boar and Tiger
Wind Bullet=2109, Rat, Dragon, Monkey, Boar.
Fire Breath: 5874, Ox, Tiger, Horse, Snake.

Why shouldn't i? XD
Already done since the beggining of the post i think.

I didn't said that they would lose their hidden jutsu because of that, just a way to say, right now if you get POW, you are going to need a Prison for them, you can do a breakout or the Kage do a rescue mission, because they will recover lost forces, but the enemy can execute then at any moment.
It's just a way so the community will right now give ideas about it, even if you are planning it already, the community can say something you don't, well, that's what i think.

Oooops, sorry, it's Land of Volcano, not Hidden.
I just woke up, so i may be saying some tard stuff.
