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.
It's looking like control hunter might be a thing with this expansion. When the class was developed the devs idea for the hero power was to deal damage slowly the opponent over time, not burst them down. Maybe these new cards will make such a play style viable.
