Yes, it most certainly is. It's also each players prerogative to decide how they want to spend their time. If someone wants to log in for the night and they don't feel like wiping while helping someone then that's their choice and you need to learn to respect it. People value there time, and you are in zero position to demand or expect anything from them. Your posts clearly paint a picture where you expect people to help just for the fun of it. So you are a prime example of the kind of person who expects time from these other players regardless if you earned it from them. Just because the game is played together does not mean people owe you anything. That's practically the definition of entitled which google defines as "believing oneself to be inherently deserving of privileges or special treatment." We all worked very hard for our wins and for the skills we've obtained by running tougher content. Then you expect to walk up and just get help from everyone because it's a multiplayer game and we all play together? You get no special treatment or special privileges just because we all play the same social game. Your reasoning falls flat and clearly defines your position as one of entitlement.
If you're on this forum denouncing those player selling runs, and by trying swaying them through the community as you suggest you are also effectively trying to force people to play the way you want to because you disapprove of the way they are currently doing it. Stop trying to tell people how to play. Not every person out there shares your morals, your code, or your ethics. You need a bit more "deal with it" in your life.
It's as simple as this Nyaruko. If you want people to have help then by all means. Go learn the fights and join random party finder groups and help people out yourself. I'm sure you'll become well known and respected on your server for doing such a thing if you do it enough as it is indeed a noble thing to do. However, don't expect everyone to be so selfless with their time and don't come here and rip on them for failing to do the same. This game isn't a charity. Every player doesn't want to jump into party finders all white knight style with their cape blowing in the wind.
If you see any of his other responses in other threads you'll see he does this a lot. He avoids the part of the response that raises a good argument against his position every time. Then he attempts to nitpick the most inconsequential parts of the response. Just wait. He'll do it again soon.
