User blog comment:Willbachbakal/(Summoner Spell Concept) Fade/@comment-6061249-20130815170235

The idea is good and i've been thinking about something like this too, but the problem is, 210 seconds of cooldown for 1 second of stealth (or 1.25) is too much. Maybe instead of removing fading time from mastery, cooldown reduction should be applied.

The note "does not breaks stealth" made me laugh a bit.
