There is also nothing wrong with wanting to help to improve the game by giving GOOD feedback or to voice your opinion. It's only the way people do it that is completely wrong and looks like they are all infants.
This is very understandable but from my experience of sitting on the official forums multiple times a day for a few weeks now this is really not the case in most situations. Most of the time it has nothing to do with the game changing. Most of the time it's that Blizzard give us something great and then people complain but are being very unreasonable. We get LFR, a great tool to experience content and gear up through. Some person does LFR for one week and gets no drops and makes a thread on the forum without any good arguments, it's just a big whine thread. This has absolutely nothing to do with wasted investments in the past and roughly 75% of the threads are like this.So when changes are made to the game, which causes them to not be able to achieve anything valueable in-game, they will loose interest but will also get angry. They already have invested quite a lot and now suddnely, without them having any say in it, things change in a (for them) unacceptable way. This makes all investment of the past, a waste. So they will vent their anger.
Also when the game-philosophy changes, this will happen.
This has nothing to do with you being entitled because of your investments and having the right to vent. These are just people being extremely unreasonable. If you think this behaviour is right then good luck defending it. I will never ever in my whole life give something to someone when they act like that.
