Being a hunter, I strive to emulate the strengths I see in my opponents. It is possible to turn the battle in your favor by simply knowing your enemy well, <name>.
In a place called Felwood, north of Ashenvale, the creatures have been tainted by a substance called fel. The bears and wolves have been driven mad by it, but I believe that they have also grown even stronger as well.
Go, <name>. Travel to Felwood and face these beasts. Learn for yourself if they are truly as strong as I believe.
It sounds from your descriptions as if the creatures show a mindless ferocity...
Stay alert, <name>. It would be in your best interest to learn more of the corruption. Always know your enemy.
