Awesome all/all Velious gear?

[Tecmos Deception]

Everyone on here likes to talk about how the all/all gear in Velious is what makes monks so tanky and gives shamans that godfactor when it comes to soloing. But will this really happen before Velious has been out for ages? Or are these items really so common (and/or obtainable outside of high-end raids) that guilds will be giving them to dps and buffer classes before all of the real tanks are decked out?
