You may overvalue mana. As a mid laner, you usually get blue buff (with the exception of the first one). And there are very few champions who needs more mana regen than blue. Some people might even say there is no champion. For the cdr, you can get it quite easily, with runes, with masteries or dfg.

Just look at it without the mana:

90 AP, 40 MR, 15% cdr

70 ap, 57 mr, -20 magic resistance

The Aura makes up for the ap you lose and cooldown reduction is not that hard to get. What it comes down to is how much the mana regen is worth and that's often overestimated. You also have to remember that almost every champion has some magic damage. The only champions who don't have any magic damage are Draven, Olaf, Riven, Talon, Trynda, Vayne, Twitch, Urgot, if I didn't miss any. And you should also think about items benefiting from the aura. All the on-hit items deal magic damage, thus benefiting from the aura. on-hit teemo would love that aura for example.

Short version: Don't overvalue mana regen, don't undervalue Abyssal Scepter's Aura.
