The point of LFR is to be easy, to let everyone see the fight. This stacking buff actually means they can err on the side of difficulty, since even if groups wipe, they'll get buffed enough to overcome it. It'll probably mean less people leaving after a wipe too. And if you don't wipe in LFR, it has no effect whatsoever.
The LFR brutal nerf for each wipe is ridiculous, people should learn the fights, LFR is never that hard, now you can just wipe on purpose to OP every boss ignoring almost all mechanics. As for Nat Pagle, they only had to increase the catch rate of the fishes a bit. 5.2 will be the insta-exalted patch, everyone will be exalted with everything regardless of time played.
In regards to the LFR nerf, rewarding people for failure is not the way to go blizzard. If you suck the game should encourage you to get better, not encourage you to keep being bad.
Still, I just don't think failure should be rewarded, you should beat it because you learned to overcome the challenge, not because you failed enough times for it to become easy enough for you to beat it, it encourages a player to never improve, because they can fail and still succeed.
You must be lucky on your LFRs because in HoF and Terrace tanks and dps still fail badly, gonna be even harder finding good players after the LFR nerf
Then if you run LFR, which is the theme park version of raids, you'll just have to suck it up and deal with those people who treat it as a joke.And by a job, I mean they just want to get in, kill the crap, then get back out and go back to doing the 'real' content with their guildmates; that's definitely how I feel about it.
