There's a couple of posters here on the forums that enjoy to "white knight troll". Every time Turbine makes a change that is unpopular with a larger group of forum goers, they like to pop into threads full of upset players and start to defend the controversial change relentlessly - and it doesn't matter one iota what the change or nerf pertains. It can be absolutely anything - as long as people are getting a bit emotional towards Turbine they smell an opportunity; all under the guise of defending Turbine from a "vocal minority".
They probably think this kind of behaviour is safe from moderation, since they're pretending to be a "white knight" of the "damsel in distress" - Turbine. What they really are doing, of course, is trying to rile up other posters as much as possible through taking advantage of whatever emotions said nerf has stirred up.
Just do like I do - learn to spot them, which is not hard once you know their modus operandi, and then just largely ignore them. Like all trolls caught in the light of day they are totally, absolutely harmless
