I just noticed something funny about protobelt
At the end of the dash, there is a brief delay before the champ can move again. I don't know if this is intentional or not, but it kinda defeats the purpose of a gap closer if you can walk the same distance in the same amount of time it takes to dash.
In the video below, you can see Morde using protobelt to catch up to a fleeing Illaoi, the result is the same as if he had just walked instead. All probelt did was apply damage, but the distance between the two remained almost the same

Let me know your opinion on this.
