How about naming it a "Sapphire augment of toughness". Things like False Life, heavy fort aren't exactly optional, and yet you've found a place for them. This isn't something new augment we're asking for, this is an epic augment we've had since the system went live. Your post is a sad excuse for over looking something that shouldn't have been over looked, period. Whoever made the decision to remove this from augments is completely out of touch with the player base.
Gearing is hard enough as it is, it was annoying when u14 came out with a ton of variotions on some gear (like dun'robar seals). Then you added levels to the loot based on where it dropped (from normal to elite). Now you guys are combining the system so that each dragon helm has what, 18 variation (6 per each of the 3 difficutlies), and then you remove something that helps us deal with gearing? We "get" to play with 1/2 a system, 1/2 our gear converted because we can't fit in toughness. Now we have to make sure we can get it before the u17 because it won't be available afterwards for even legacy augments.
You guys won't release the enhancement system "until it's done", but have left us with "beta" crafting and are now putting out 1/2 the augment system? You even killed one of the big advantages of guild slots when you did so.
Personally, I'd rather you'd spent whatever time went into revising older, non-epic low ml loot into making sure the level 20 + augments were ready.
