[b]Uchihas and their usage of sharingan in IC.[/b]
The Sharingan. My concern pumps up after seeing it used by Renny which is no problem. Anyhow:

We know what the eyes can do. Based on my nerf:
One swirl; sees chakra, anticipation aka precog. Users of this only get a 0.5 difference in their overall status.

Two swirl; Retains what the previous stage offers but 0.5 enhanced making it twice in this stage. Users of this gets to copy techniques which a one swifled cannot do. As well as mimic pencil like movements. Two swirled stage cannot see through genjutsu by my standards.

Three Swirl; The highest form of what every Uchiha in this RP can get unless I allow MS. Users of this retains previous stages powers but more refined as they can now copy techniques at near accuracy of 100 percent. Lip reading applies only in this stage as well as genjutsu cancelling. The users will get a two times status boost of their base form aka normal self. Genjutsu cancelling is not instant. Genjutsu hypnosis requires strictly eye contact and it takes time to cast bit ain't slow. It is only slow cast to PCs but instant to fodders. The ultimate weakness of sharing an is truly sound genjutsu because it is not visual. Any other way to counter sharing an applies. The way to break sound genjutsu is when two sharing an users are together.

No Ms and beyond.
