Influx of new jerks? Or just old jerks emerging recently?

[Solb]

Has anyone noticed in the last 3-4 weeks or so, the influx of jackasses now? From the first time I logged in a year or so ago, till most recently I had more pleasant experiences with the players base.

Now, suddenly over the last few weeks I personally have had more issues over camps, more experiences with players refusing to group others due to class/xp penalty etc., when the class would work just fine in the group... ("We have a cleric, we don't need another healer", when the camp is a lower lvl dungeon and any class would honestly do just fine filling a spot in the group).

I seen a 3 man group in MM, refusing to group anyone else at a major camp spot because "We hold the camp just fine and get better xp this way, why would we invite more?" The truth was, they had mobs sitting up in spot, and when others began to pull them because they would not get invited to the group, the group ragequit and finally left... But, why?

I could list many other situations, but this stuff really didn't seem that prevalent when I first started on the server. Was I just lucky before, or is there indeed an increase in trolling/poor behavior amongst the player base now?
