The current Dalaran Underbelly PvP/FFA crisis points up exactly what is wrong with the WoW community and why it is toxic.
The game encompasses all kinds of activities and playstyles. There is PvE, PvP, crafting, exploration, dungeons, raids, questing, world mini-bosses, etc. There are things for everyone to do even if that is just gathering or fishing. No element of the game should ever be developed at the expense of others in the game community. Sadly, many of you seem to actually enjoy when others are denied their fun and are placed within your grasp so that you can grief them. And this is additionally encouraged by Blizzard that creates content for this kind of shortsighted pandering to one segment of the player base. Its very odd that they pander to a small group that way because their success is entirely reliant on having appealed to a large audience with very varied playstyles in the past.
Most of you are looking at what you want out of something and by all available evidence unable to see how that works out for the other guy. You don't care about the other guy's experience but you should. The other guy is paying just like you are and his money helps keep the game afloat just as much as your money does. The more players they lose, and many are gone already, the worse the game gets and the more pigeon-holed the development seems to become. The target audience is ever smaller and smaller.
If you love the game you must demand that Blizzard develop the game so that you are happy with it but so is the other guy. There is a time and place for everything in the game and you just need to encourage Blizzard to build and maintain the game that way. Letting the other guy get screwed so that you can have some temporary fun is basically cutting off your own nose to spite your face.
I'm just going to press the point one step further and state this problem is not just a problem in the game but a problem in life and society as a whole. You can't ever let any one group of people bully another, because eventually they come for you and yours too.
Most of you don't know me, I only dip a toe in here once in a great while and usually for only a short time. But all I do is PvP in the main. I am exactly the type of player that Blizzard may see themselves as specifically pandering to with the current state of the Dalaran Underbelly. I am not now playing the game, but even if I were I would oppose the way Blizzard is handling this matter. Why? Because I care about the game and I know that when most of the players are happy with something the game is healthy and has a good chance to progress. There are dozens of ways I can indulge my desire for PvP, but forcing it on PvE players is not one I would consider either good for myself or even good for the game.
You need to care about the other guy and his experience in game. If you don't, the game is surely going to die by a thousand cuts that you are cosigning with your indifference.
This is quite literally how a society thrives and survives or how it dies, fractured with each person defending only their own little space. Taken out in the end, one by one until none are left.
