Archers lose the ability to charm animals
The natural bond an archer has with animals is not as strong as that of an ordinary ranger or a beastmaster. I think this is meant to be in the game (I've got the same thing), but it could also be a bug (although in that case the official patch won't help) Nonetheless, archers are powerful enough already without the charm animal skill.

The last arrow of Legolas kindled in the air as it flew,
and plunged burning into the heart of a great wolf-chieftain.
All the others fled. -J.R.R. Tolkien, The Lord of the Rings
