Instead of forcing the use of Acquisition Range, which is important for game play, you could use the new native to get the unit's actual range.
The added benefit is that for maps well on their way to finalizing won't need all their units to have their Acquisition Range changed. Otherwise, this could become a hassle for these developers. For maps in the early phrase of development, less unnecessary work would be granted to them. Of course, third party tools could also circumvent this somewhat tedious work, but to install a third party tool for just this may not be well received as the past have dictated.
At the same time, the native makes it possible to get the ranges of both Attacks if the unit has a second one. In addition, via standalone functions, one could display range in any situation, not just during a spell cast.
A while back, the new native was mentioned as dysfunctional in List of non-working object data constants. I have tested the new native in the latest patch, and it is working fine.
For spell cast, just code a demo that peeps can copy to their map like so.
Aniki, at one point, also made a similar system, using images for the display. His could benefit from automatic range detection.
