Dude, kill the Uprooter. Finish your quest. Move the **** on. Dont spoil the game by sitting there killing it repeatedly. Forcing low levels to sit there gather in hordes hoping for a kill they wont get, cause you're being an ass.
gain some levels, come back and out damage him. Profit. i didn't even bother with that quest because I would have wasted so much time competing with everyone else to get the scratchback item let alone kill the thing. So i got to OC 4, walked up to the 10 + people waiting for it and killed it almost instantly. Don't whine because there is a troll. They are everywhere, so work around it or else your are just wasting your own time.
Good for you? Its a community thing. I'd hope you'd understand that. Whats stopping that troll from getting bored and coming back at SM and doing the same thing? There needs to be consequences. Just like pk has jail system. Killing Lowbie bosses should have some concept along the same lines.
