I think Pyke's R is overloaded.
Pyke is a cool champion design that is fairly balanced (imo) besides his ultimate. He's a support with a Grab, a stun, stealth and a:
Resetting, aoe execute that doubles kill gold (so 2 first bloods), ignores shields and ignores armor/mr, and is a slight dash, with a small cast timer, AND the people that can be executed don't know it.
, it's not easy at all to hit his ult in a teamfight, and if you miss it y(either hit the wrong target since it's AoE or the enemy got healed, god bless
gaining 1/4 of his hp with one aa) you'll just teleport in the middle of the fight
