Dont forget that LFR has only existed since DS in Cata. Before that, yes they have nerfed bosses when they have been out for a while (and earlier if they discovered something unintended). Giving the hard core a chance to do it before nerfs then making it easier for others is a good move in my books. As far as LFR goes though, I do not agree that it has got easier and easier. Some of the SoO fights are way harder than any LFR fights in DS for example. I think one of the "problems" with LFR lately however is that a lot of people that didnt feel up to normal mode, but could handle more than LFR have moved to Flex and no longer run LFR. This means that some of the better players that used to run them no longer do. Having said that, some of the worst players I have seen in LFRs are very well geared normal raid players who literally stand in fire and auto attack. The problem is that with their gear they still do fairly decent (or at least not really BAD) dps so they are often missed. Lately I've seen more ravagers spawn on Nazgrim due to people just standing in shockwave than I've seen by them attacking in defensive mode. Its almost comical.
