With Kenbunshoku haki I think it would be cool for there to be a small chance to randomly be able to dodge an attack (like with future sight or paper art) depending on the speed or frequency of the attack. The chance to dodge should increase the more you level up your observation haki. Future sight and paper art will still be abilities but will be used as guaranteed methods of dodging rather than the random dodging from observation. This should add incentive to kenbunshoku training and make it a bit more accurate since we see many haki users incapable of future sight using kenbunshoku to dodge attacks. 👍
