I can give an opinion as a reasonably well-equipped PvP hunter (not 100% optimal but decent): in this context, the
feral druid is powerful and
extremely resilient (bear form), almost to the point of being unkillable (considering that in a tough spot, they can heal, control the distance, etc.). Honestly, my only way of not dying against a well-equipped and well-played feral druid is often to trap and... run away (which unfortunately isn't the solution in all contexts). If I kill them (which happens rarely), it's because the druid made several mistakes and/or has significantly inferior gear.
A top-tier class in
ALL BGs (stealth/speed in cat form, and the ability to absorb damage in bear form)
Unless there's a huge nerf, you won't be useless at all, and with a bit of gear, you'll even be very useful.
PS: Of course, a magic damage class might not feel the same in 1v1, but I think we can all agree on the impact of druids in BGs.
PPS (edit): I hadn't realized the topic was actually quite old
