Suggestion to make the stat tracking microtransactions more interesting

When you have a stat tracking scroll(s) equipped, for example the one that tracks how many monsters you have killed, after reaching a milestone (e.g. 50k killed monsters) it should show a big nice number above your character and play a satisfying sound. I think it will incentivize players to buy those microtransactions more and make it more appealing. Dota 2 does this and I think it looks cool in that game. Just my 2 cents.
