There is actually quite a lot of debate over whether the new MM is "an attack".But you are still making a Ranged Attack, you're still prone to Opportunity Attacks, and you're still affected by any "attack an ally" mark effects.
I have no opinion on this issue: there are significant exploits for both interpretations, so IMHO balance won't perfect either way.
