They need to appeal to both masses. Raiders and non-raiders. So they will try to make the gear sit on equal grounds. If they don't give non-raiders their own way to get a high ilvl weapon then it craps on the non-raiders (even if you literally don't need anything better than 110 to do non-raid content, but that's besides the point).

I thought last tier was done well, the 115 relics came out near the end of the second coil lifecycle.
