Whats with the sharingan?

[Krbadass]

Well you don't know that, thats only a speculation because it hasn't said that in the anime.

Forget about the dots and the jutsu's for a minute.Look at it this way,more dots more growth.Just like the human body develops,more things develop.When the sharingan grows,more dots appear with 3 being a full grown sharingan.Nothing anywhere has been said as to what each comma represents,so that's all fanfic.

there is no reason for the sharigan to gain more then 3 commas
masters of the sharigan have 3 commas, they control EVERY aspect of the sharigan
sasuke has only 2 commas because hes only a novice with it

and just to clear this up, using the sharigan consumes chakra, no matter whos using it

Of course you don't know this, cause it hasn't said it in the anime, good speculation though.

I have always been wondering this... I hope we'll find out later.
