people have to see it as a blocker. We can all see it, but if your drafters don't then it doesn't play as intended. Have you guys actually read through the Gatherer? About half of people commenting realize it's probably meant for trading on defense.Emissary is fine as a blocker, trading with a lot of attackers is solid. I don't see the problem with the card.
EDIT: This top post on Gatherer is basically exactly what I'm getting at:
VE tricks people into thinking it's for an aggressive midrange deck. Primal Druid doesn't lie to you about being on the defensive line, and that's why I think it's read slightly worse but might play better overall"Looks good on paper, but is pretty bad in practice.
Played 4 of these dudes in a besieged draft and found it almost impossible to get the land with any reliability- at least not in time to drop a T3 blightwidow/vatmother. I'd have prefered a 1/1 with infect for this- at least people would actually block it."
