Hiya dante mate!
Alo
Hope you are keeping well?
As well as preservatives can keep a zombie.
Being able to see into another dimension and prevent ethereal opponents from spying on you with impunity isn't worthless. It's actually quite valuable.
I used the term etheric to imply 1st Edition ethereality which implies ghostly which implies (3e) incorporeal. Just leave it as it is.
Again I wasn't referencing your use of the term etheric. I was referencing your description of WHY the ability lets you hit incorporeal targets...
"Your vision extends into the ethereal plane." - KRUSTY THESE ARE YOUR WORDS
...you must have missed it.
Also, 3.5 is VERY CLEAR that ethereal is NOT incorporeal.

Incorporeal vs. Ethereal
Many people confuse these two terms. Some of this confusion
revolves around the ghost, which can be both ethereal and
incorporeal, depending on whether it has manifested.
An incorporeal creature is visible but can’t affect (or be
affected by) corporeal objects, except as described above. It
still exists fully on the Material Plane, despite its inability to
interact with most objects.
An ethereal creature exists not on the Material Plane, but on
the Ethereal Plane, which overlaps with the Material Plane at
all points. An ethereal creature is invisible and insubstantial. It
can see and hear creatures on the Material Plane, but everything
looks gray and ephemeral, and sight and hearing are limited to
60 feet. It can’t interact with objects on the Material Plane in any
way. Even most of the limited options available to an incorporeal
creature—such as ghost touch weapons and armor—don’t
work for an ethereal creature, though force effects still affect it
normally (since those effects extend from the Material to the
Ethereal Plane). An ethereal creature need not abide by the
incorporeal creature’s limitation of remaining adjacent to an
object’s exterior. Finally, an ethereal creature interacts with
other ethereal creatures or ethereal objects as if both were on
the Material Plane.
Ghosts are ethereal unless they manifest on the Material
Plane. A ghost on the Ethereal Plane is not incorporeal and
can affect other creatures or objects on the Ethereal Plane
normally.
A manifested ghost is incorporeal on the Material Plane, but
also remains partially on the Ethereal Plane, where it can interact
with other ethereal targets normally. Its spells can affect targets
on the Material Plane as well, except for spells with a range of
“Touch” (ranged touch spells work normally).
