The entire game is pretty much already assessable to everyone (5/10 mans, BGs) , the only real PVE challenges are the high 25m raid instances and arenas on the PVP side. If you nerf those so that they can just be zerged down by anyone without even trying (or make the arena system moot), then there would literly be no challenge for any vetern players. People would buy the game, level a guy to 70/80, and then just quit or possibly give up sooner as they would feel like the game has nothing to offer except the leveling content
