Well i never say it predicts FUTURE position of the ball,it only predicts where AI need to be with it current speed to intercept a ball,not where ball actually will be.And on top of that it also allow ai to get a chance to see if he can pull some fancy move.And more skill also change how it will be moving.
For ex. with AI skill 90(90 from 100 bassicaly) every few seconds(around 5 sec) bot checks if play can be done.If it can,bot will also check if specific(random from list) move can be executed.But this move also need to meet a criteria like angle and speed to succeed.
So even if AI succeed in check for skill,it will still need some conditions to pull a special move.And most of the time it can result in fail.
Anyway with low speed you will, most of the time, take damage even with hi skill stat,cuz ai cant even get to a ball in first place)
If you want to go for skill build better choice will be PANTHER,cuz this class have high speed from the start
(160% i believe)
Its all very simple,but hard to explain how different stats and mechanics works.
So try different builds and see that will happen)
