Hm.... I know the proc hit more then 1 target so it can do up to 400 damage per proc but why would or should i get this over Wit's end which does 42 damage per hit so i would do like 168 damage on the 4th strike and grants me 50 MR if i keep the stack.

I can only assume this is useful for defending so you can kill minion while hurting the champion attacking you.
