That’s actually the root issue.
The “everyone needs to play what I want and how I want” players and posters really are struggling with interpersonal relationships in the virtual world. They believe that they should be able to log in and immediately have a bunch of people willing to play with them, doing the content they want to do and performing it the way they want them to as well. In short, the world revolves around them in their mind and it’s very disappointing to learn that they can’t force all other players to conform to their wishes. Thus they insist the developers force their will on the rest of us.
The real issue is self-centeredness. Not leveling speed/rewards/powers/whatever.
I think self-centeredness is the focus for most MMORPG players. It's not necessarily a bad thing.
Let me be transparent - I don't play DFB, and I don't PL - I enjoy the grind. It's a badge of honor for me, but I don't expect it to be so for anyone else. I also don't think we should try to stop PL'ing - it's a reality that's going to be in the game no matter what. When it affects other players - then we should discuss. I don't support nerfing or changing DFB at this point - not where I would want developers to spend their time.
Back to self-centeredness - for every player on this board advocating against DFB, I'm sure I can find a similar number of players complaining about AE XP being nerfed, or Vanguard Merits, or what not. And some of those AE folks don't seem to care about the server issues it causes - they just want their XP, the heck if makes the game unplayable for everyone else. Pretty self-centered.
RP'er's play to role play and advocate for the name change policy to support time spent in toon, not the level, PVP'ers advocate for PVP changes and things that encourage PVP, PL'ers advocate for things that let them PL faster, Min/Max advocate for power changes that make them more uber, and grinders' like me advocate for more content driven changes. It's a game - we don't play it to be selfless, we play it to be self-centered. We aren't here to actually save the world.
As for people "insisting" the developers do things - I haven't seen that behavior in the OP. It was a request. It wasn't "do it my way or I'm leaving". Not really clear why so many requests on this board that are made turn into people projecting that OP is demanding something of everyone else. It's a request...right, wrong or indifferent, it was just a request. Don't like - say so, love it - give it a plus one. But tell the OP they they are selfish, or demanding, or insisting, or hating unless that's what they are actually saying.
Finally - It can be hard for people to team up. Again, we are all self-centered, we all want to find a group that plays the way we do. I was asking for people to team with me last night to help with my missions - no takers. Someone finally took pity on me I think and invited me to a group that was way overpowered for their missions and I was pretty useless. 90% of the damage was done in the first 10 seconds, and the remaining 10% in the next 10 seconds. It's not how I play. I thanked them (they weren't rude, in fact they were very nice) and went on my way. After asking 3 other people thru tells if they wanted to play, I got tired and gave up. Did I take initiative? Yes I did...How did I feel? Frustrated (though not at any person, just in general), and a just a little rejected. I don't take it personally, no one was rejecting me as a person, but it's still not a very happy ending to the story. So please don't tell people that it's all in their heads if they can't get a team they like.
And you DFB players would be very disappointed if no one wanted to play DFB teams - so it's easy to cast stones on others because you've already got all the people teaming for DFB that you could want...
See the thing is, you're not going to get the exact team you like at any time of the day at any time. The line of "your experience is subject to change" that had been used for years when developers describe their mmos is factual.
Sometimes the teaming will be fast and sometimes it will be slow. That's just the reality.
That does not mean there is anything wrong with the content that folks are doing at that particular time that you don't want to do.
I think folks are just frustrated with being told constantly that their way is not the right way to play, just because they choose not to be available to play with everyone 24/7.
MMO or MMORPG means you will be around players 24/7.
It does not mean that all of them, or even some of them, or even a fraction of them will want to team with you.
