Mage players across the League disagree on a lot of things, but one thing they can all agree on is that one of the most obnoxious items to enter the game in some time is the now ubiquitous Edge of Night. In addition to providing respectable offensive and defensive stats for the cost, Edge of Night can also be activated in order to provide a long-duration spell shield that makes it hard for mages to lock down anyone walking the path of the night.
After the recent lethality buffs, Edge of Night started taking over the game completely. With the rise of AD mid laners such as Jayce, as well as assassin junglers such as Kha'zix and Rengar, it's not at all unusual to see five of six Edges of Night in a single game, a fact that has pushed a number of traditionally dominant mid lane picks such as Viktor, who relies on long-cooldown skills for the majority of his damage, right out of the metagame.
Thankfully, the Edge's reign of terror may soon be over, as Riot has identified the item as a balance problem, which traditionally means that it will get nerfed beyond the point of usability. The first step has already occurred, according to Rioter ManAxeWolfBoss who claimed in a tweet that Edge of Nerf was stealth nerfed yesterday. According to him, the items now has 5 less attack damage, and the active shield now has a 15 second longer cooldown. The cooldown change, in particular, is a godsend, as the item's prenerf cooldown was barely longer than it's duration and began counting down once the shield was activated, not once it was broken, meaning it was available practically all the time.
The more important revelation, however, came later when ManAxeWolfBoss also revealed in another tweet that the nerfs to the item were not current revealed on the item tooltip, a bug that's become increasingly more common as time has gone on. For the majority of the League community, then, the nerf to the item is likely to go unnnoticed, even though the official patchnotes have now been changed to reflect the change. Considering the tweets that announced the changes have had very little reach thus far, make sure you tell your ADC loving friends about the change -- they're unlikely to find out otherwise.
