The reason its a Beta patch is because its still being tested and being fixed for bugs and game balance.
It will be implemented once all the issues (hopefully) have been sorted out and it works fine 100%.
That's great ~except~ no one is near lev 100 there. So if they wait it could take a while to see if the bloody thing works. That could be weeks away. SIGH At least it's a step in the right direction.
