You and McBeth have no clue, are guessing, and are guilty of being snide to everybody based on your (without evidence) guess. Perhaps you're both even guilty of assuming that this was some balance to flow of shadows, and therefore the ridiculousness of flow of shadows was rational because there was an easy and obvious counter (you guessed). Meanwhile, it's highly probable that faerie fire has no such affect on flow of shadows. We even have a tiny subset of data suggesting it doesn't. Shame on both of you for both spreading misinfo.
