Skeleton without a weapon is passive

Hm, what should the helpless skeleton do ? Rattle with it's bones ?

I dunno, the same as a zombie, or even Steeve without a weapon. The skeleton should fight dirty with its bones instead of just ignoring the damage done. Even the animals run when they're hit, not the skeleton.

Rattle, rattle.

I'd like to confirm this issue, but

/summon Skeleton ~ ~1 ~

spawns Skeletons with bow.

Indeed sorry, the exact command I typed was

/summon Skeleton ~ ~1 ~ {Tags:[mob]}

I suppose the fact that I add the tag part overrides the default bow.

Cannot confirm. Skelly is hitting me to death with it's bare bones.

Hm, can confirm. Don't know where the difference between the first and next skeletons is.
Derp. Creative mode.

Cannot reproduce in 15w33c with either

/summon Skeleton ~ ~1 ~ {}

or

/summon Skeleton ~ ~1 ~ {Tags:[mob]}

(both summon the Skeleton without a bow)

Well if you cannot reproduce I suppose I did something wrong. Sorry for the bother.
