Ok, seriously, why does Pyke warn the enemy of hiw presence way before he gets in vision range?

He already has a very largedetection radius, so why does the enemy get a warning when you go camuflage half a map away from them too?

This really cripples the Champion, the only times I was ever ganked by a pkye was when I wasnt paying attention, all other times its just "Oh look sharks, that means pyke is somewhere around, but still far enough away that I can just casually go to my tower and chill until hes gone!"

Really, no other Champion has such a self crippeling mechanic... Why Pyke? Hes not even that scary overall, so why make him even weaker by allowing the enemy to see he is coming from a mile away?
