And when a tank is nearly 3 shotted by trash mobs ( and being decently geared ) there is something wrong. Challenging I understand, but insanely hard is another. Most people will not queue for these new hardmode's because of so many factors.
Are you tanking naked? I've had time during hardmode flashpoints to refresh Kolto Probe, cast Kolto Infusion, and walk away during a pull for about ten seconds to change my air conditioner. Seriously, they aren't that hard.
