These are very good for young Rangers and possibly Druids who want to work on secondary weapons skills after your primary has maxed out for your level. If you have some decent armor then you will get a lot of swats at these (when they con dark blue) to get those weapon skills up. I like to snare them and shoot a few arrows at them, nuke (haha, our nuke is so weak at lvl 20) them once or twice and then melee the rest of the way. You will need much mana for healing after the fight, but your dual weild and double attack skills that you just acquired will go up faster than normal. And you can work on your secondary weapon skills (for me this is piercing and 1H blunt) as well.
