Starting with ToV expansion, it was very apparent that the game was steering towards rewarding those that crafted, with more than just furniture and appearance items and players that did both, adventure and craft, would have the advantage. It was just a matter of time before it would be required to get BiS and / or necessary item(s). 2.0 is necessary for raiding as it protects the player from planar energies. It does allow one with the epic to cast that same buff on another in the raid that does not have their 2.0 yet and earlier in the game, we did have raid members that we had to cast the buff on to protect them and the raid. As far as 2.0 being necessary to get a group, that is just silly.
