Horns of the Ox and Spirits

I have been doing some PvP with an assassin, and by some I mean sevral days. Through all this fighting one thing has continuously bugged me.

Ritualists can be completely immune to the skill "Horns of the Ox" by simply standing next to their spirits, or protect their team with excesive "spirit spamming". (This involves the Ritualist practically making another team out of spirits, as well as being out of nowhere, unlike minions).

This lead me to a conclusion. The skill Horns of the Ox should be changed so that it is:

Dual Attack. Must follow an off-hand attack. If it hits, Horns of the Ox strikes for +15...27 damage. If struck foe is not adjacent to any non-spirit allies, that foe is knocked down.

This way spirits would provide no protection from this move, which, if you think about it, makes sense. This skill is obviously a physical hit that knocks a person over, unless someone else gets in the way. Last time I checked, a spirit is not really a physical being (unlike a minion) and so should not be able to "give support" to the person.

The spirits give it's allies' spiritual support, but last I checked, you can't walk through these things unless you're a rit who didn't move when he/she summoned them.

I think I'm wrong, anyway, it's just one skill, no biig deal

I'm undecided, leaning towards /notsigned.
