Adding Cooldowns to Abilities with the gameplay ability system in 5.3+

there is a bug where the instigator of the effect is actually the player and not the ability

Instigators are the “causing actors” of whatever an effect is. A Gameplay Ability is an UObject, but not an Actor, and thus cannot be an Instigator. So, the Instigator being the player is intentional, not a bug.
