It doesn't matter what orange blank you use, any crit crafted orange with have an augment slot. The new armors released with 1.2 have the set bonus attached to the armor mod.
So using crit crafted orange gear and the mods from the new armors (campaign gear for pve and warhero for pvp) That is currently the best armor in game.
I wouldn't grind too hard as they will be adding the ability to put augments on any armors in a future patch, Just concentrate on your battlemaster set and you'll be fine, then start replacing them with warhero pieces.
