Calm down, CS. Esus has obviously read your posts, as have I. Elums are much used by Mudokons. If Elums are really so unusable through laziness as you say, Mudokons wouldn't utilise them so frequently. The facts that he can run faster and jump further speak for themselves why Elums are so important.
Additionally, a Slig could not easily shoot if he's unarmed.

And he couldn't move out of the way very much if he was without pants or asleep.
