dont nerf... FIX
How do you propose we fix things like this? Nerf the weapon? Or nerf the quest for higher levels to get it? A level req. really makes things alot easier, and you can just get the extra few levels, really. It's the goal of most people to progress by leveling, so it shouldn't be that big of a problem to get a few more levels.
Nerfs are just part of the Onling RPG experience.
