Its only easy to get those if you purposefully hang around those levels to try to find them. What if you're a mage? What if you don't feel like stopping to regear every 3 levels during your lowbie ranks? Etc. Like I said, your viewpoint is naieve because especially in the low ranks things aren't balanced so there's a lot of matchups where one side of the matchup has an easy win if they have half a brain. A good example would be rank 28 human Shaman vs rank 21 cloud warrior, for precisely the malediction vuln that you mention.
I don't think anyone would post about this guy if he was a fire giant but as a neutral that's bad roleplay.
