I personally love when they do this, sure I can see some people getting upset about not being able to view this themselves personally but that should drive them to get better and hopefully one day view this personally. I DO hate when they pick and choose these variances, for example in Cataclysm, Ragnaros had an entire story/phase of the fight dedicated to the defeat of the Fire Lord. However when it came to Deathwing, there was nothing special, the fight looked the same on LFR as it did on Heroic. From a consistency stand point they need to either do every fight this way or none at all just my opinion. I'm all for the fights being more epic and engaging. For the complainers, did you sit back and whine when you didn't get the extra cut scenes in Metroid showing Samus as a female? This isn't a new strategy in games, and beating games on higher difficulties has ALWAYS awarded the player in some form.
