1: Just a sound effect whenever you proc it would be oh so helpful, because there is almost no indication when it goes off

2: When you hold TAB and mouse over the mastery it tells you how many times you have procced it this game

and this last one isn't necessary, and it might be difficult to implement but it would help a lot too

and 3: I got this idea from the new phantom dancer, but have it similar to PD so that you can see how many times it secured you a kill. You could probably do this by coding it in that withing lets say 6 seconds after you proc it, it counts as a kill for the sake of the counter.

I love picking it up on certain niche champions, and even though I know it's good it still feels a bit underwhelming. Just these few small changes and it would be so much greater
