Pyke ult priority needs an update (situational)

Pyke ultimate is great, an incredible ability which carries amazing cc. So obviously you think "What if I give it max mana from start so he can ult right away after he jumps to his target" Well that's not how it works apparently, I gave him Shojin's and Seraph's which maxes his mana from start and he ults from his starting position to a target, which his ults targeting is exactly like assassin's jump targeting, the furthest person from him, then does the assassin jump to the furthest person from there. Meaning his ultimate hits absolutely nobody because nobody is between his starting position and his new position. The priorities should be switched JUMP FIRST then ultimate.
