Yes, it does stop grid camping, mostly.
It also will probably make PVP even more non existant than it already is.
About the only meaningful thing to do in PVP in this game was to attempt to "hold" 2holes for your side. That is, if you got a bunch of players from your side in, you could control 2holes.
That was mostly broken when the changes to 2holes took place and the grid and whompa were moved apart and the omni guards were put in place. This change should be the final nail in the coffin for that.
It means that 2holes is now totally safe for people who want to do missions, which of course is what this game is all about. Doing missions and gaining levels.
It's not about anything else.
