Its ok. Just try to avoid making items that feel bad for the player who is supposed to use it
Having permanent -ms is not ok, because permanent ms is something that is needed for everything: roaming between lanes, farming minion waves/jungle, dodging spells, chasing/escaping etc. The game is just worse in every aspect when you don't have enough ms, and thats why boots are bought on every champion(with 2 exceptions)
On the other side, having an active that decreases your MS to 100 and gives something in return for a short time is ok, because player can try to minimise the penalty by positioning himself first and then using it. Of course he can misplay it and end up almost rooted under the focus of enemy ranged champions, but that's player's mistake, not the item's fault
So I should cut down the Iron Juggs cost slightly, reduce its base stats and add the additional stats onto the active along with the movement speed debuff. Sounds good
