[Gameplay Bug] Thresh's Relic Shield does not function properly
Compared to other champions such as Blitzcrank; Thresh cannot easily hit the minions with a relic shield stack and kill the minion. His auto attacks deal very little damage so you will usually have to wait until the minion is very very low to have the relic shield stack work properly. This is especially frustrating because other champions such as Blitzcrank will kill the minion under 50% health almost every time and still recieve the relic stack bonus for him and his teammate. You need to examine how Thresh functions with relic shield by testing this out in any custom game. Notice the difference when playing with blitzcrank and using the exact same auto attack.
