You make an excellent point, though I actually envisioned (pun intended) something a little different, as granting full-blown sight over terrain and through brush would indeed be overpowered. I imagined it would 1) affect the champion using it, similar to Rek'Sai, so that that his/her normal vision was 'replaced' with the x-ray 'sight' for the duration, and 2) the x-ray 'sight' wouldn't grant targetability or even certainty of who was being seen, only that someone is over there. For the visual effects, I think it would be like looking at the map covered in the Fog of War but seeing grey shapes (enemy champions) moving around within it (within a certain range of course).

Riot could also play with the direction you must face or maybe you need to channel the ability to use it, making you vulnerable. The point is that adding more forms of sight, stealth, detection, and denial makes for a healthier game environment and a more fun game overall, if, and only if, the various forms of vision have significant counterplay built in.

For reference, could you tell me the specific champs and items from DotA that do that? Or link to them? As much as I frequent the DotA2 Wiki I'm not certain what abilities / items you're speaking of. Please & thank you. :3
