You say that like it's a bad thing. I think it's great that players try to break the system, especially while it's still on the preview server so there is potentially time to fix it before it goes live. In an ideal situation, Turbine would have thought about all the little things one could do to break it, but as long as someone finds the issues before they go live, we can't say Turbine wasn't warned about it. The "subset of players" could have kept their mouths shut and just worked the system after it went live, but they are speaking out about it now. This is a good thing for the game.
