Who knows if it's working as intended, but it's certainly not working as described. The tooltip clearly describes the effect as a 'Foe Beam.' Ergo, it should only affect foes, which it isn't doing at the moment.
No need to get snippy about the semantics of the title. The first line in the post body clarifies what's going on. I get the feeling you made an account just so you could correct someone's grammar.
There is no red circle for Antipathetic Field, and even if it did, ted portion of circles signify team damage for spells that deal team damage... but they are still there for foe only spells, in which case they signify nothing in particular... like Eyestrike, for example.
