Smashing with Mace should give Slowness effect

Seems like in the latest Minecraft Preview/Beta, There was some balancing made to the Mace, its going great, but i got a small suggestion:

What if, after a certain height, a slowness effect of like 5 seconds was given when smashing with a Mace, with an effect level proportionnal to the height, maybe 1 level for each 5 blocks or something,like that. Could balance more the Mace as people would get a little "cooldown" when using the mace in PvP and its logic because hitting from this high kinda stuns you
