How do you know that kaguya's vision is 100% dependent on her byakugan. The byakugan has the best insight of all dojutsu there is no reason why kaguya wouldn't use it to improve her vision, 3 eyes are better than 1.
Yes, but there is no proof that she is incapable of vision without her byakugan either and since you are the one that made the claim, the burden of proof is on you. Given that there is nothing to suggest that her rinne sharingan is incapable of seeing things on its own
The burden of proof is not exist either on me or you. There is no burden of proof here
You make an assumption and its same with me
What did you want to proof to me here by three eyes is batter than 2?, but still all the time we saw is Byakugan style of eye view and not sharingan style òr Rinnegan style like Sasuke.
Even her Byakugan prowess is like no where to be found, she should make a difference between godess and Normal Hyuuga eyes.
Did you felt anything different with her eye power and average hyuuga eye power?
When she failed to differentiate between the clone and original or anything else, why she not using her very powerful Sharingan eye to test a water or see any differences but she continuely utillizing her Byakugan
There are many thing you need to proof to me about her eyes capabilities and expertise in using it and put aside her status and power
