Abyssal mask magic damage radius

Can we get a buff to the radius on Abyssal mask? It's honestly an amazing item, but the size of the radius is so small that its uses are pretty limited. I'd love to be able to build it on more champions.

If I'm against a comp that has a lot of sustained magic damage I sometimes build it on Morgana. The Hp and higher magic resist than Banshees seems better to me. Plus, once your basic abilities do more than 600 damage it is a stronger overall damage item than a 100 AP item in the same slot. (Do the math to verify, this is based upon Morgana's 90% ap Q ratio.)

If the radius could be doubled then medium range ap champions could build this item more often. Right now the only mage that builds it fairly often is Veigar. The damage calculations for him with the item are fairly insane, and he's rather short range. I'd like to also see it be more practical on characters like Morgana (She has to be close for ult) and Ryze.

I really do think it's an undervalued item.
