We should rework Thresh Soul passive to be more interesting
Still infinitely scaling but with a bit different functionality. Here is my proposed rework idea:
Only champs, cannon minions, large/epic monsters, and scuttle drop souls now. Champion and epic monster souls are worth more.
Souls no longer give AP and armor but slightly new functionality tied to his abilities.
His E passive auto bonus magic damage no longer scales on total AD and souls. E becomes slightly reworked on activation after you flay an enemy and damage somebody with flay your next auto deals a bunch of damage based on total souls gathered.
His W gets the biggest change in that for every soul he has his shield becomes 5% stronger. If the base value is 200 and he has 20 souls his W will shield for 400.
Souls are worth the following:
Cannon minions, super minions, large monsters, and scuttle crab: 1 soul.
Champions: 2 souls.
Dragons and rift herald: 3 souls.
Baron and Elder Drake: 5 souls.
