It should be more apparent that tomb purchased gear is supplemental. Most ppl don't know you don't even need to buy Mytho gear because Ilvl 90 drops in coil. But I guess SE is to blame for that because the content that is meant to be between ilvl60 - illvl 90 isn't even in the game yet. So once CT is here, everyone will run that for ilvl70 gear, and no one will be complaining about tomb grinding.
