You can't harass members who play Face Hunter, nor are they compelled to make preemptive apologies or justifications for playing it. They don't hack or crack their opponents' game, they simply play existing cards that form a specific deck. If you suck at countering Face Hunter, you should blame the designers, not the community.
Mindrange Hunter is absolutely going to be the way of the future, mark my words. As mentioned previously, this card helps to accelerate the clock on opponents and puts a-- while weak bodied-- 6/3 card on the board. Is it optimal at the moment? Not necessarily. But as more cards are released can I see this card absolutely seeing play in midrange? Yes.
The problem is that you can't really use it as a win-condition if priest and warrior or getting buffed to 4 hp protection and hunter is only doing 3 damage. Hunter is losing ground if both people play this card on turn 6.
