I believe nothing of the sort.
If you really do, and aren't just blowing hot air (you know where), you're likely to be a victim.
At least this game seems to inspire courteous behavior in players more than not. I'm sure, however, it's a response to the mechanics and design on some level, accounting for the disparity with more twitchy and competitive MMOs. Ditto for why players choose blueside over red. I mean, you'll even find people mostly behaving the same on that 4chan server, despite a few edgelords spamming garbage for the Lulz.
I believe he means the queue systems found in WoW, SWTOR, DCUO, and other MMOs.
And the answer to the original fella is: No.
You mean yes.
Have you not clicked that LFG tab? Sure, if you're just a low-level scrub you'll only See Drowning In Blood there, or maybe one other trial if there's a holiday event running, but it is a queue that you can just join and get added to a team for the Trial if you want. You could also gather a team, or even a League, and then join the queue, but you don't have to.
Yes.... But also kinda... It exists, but isn't very good...
The LFG finder doesn't always grab a full group if you queue solo.. It'll often go with the minimum and for much of the game content, is not enough folk to complete the mission.
I've tried it a couple of times and it often sticks me and one other unfortunate soul into an un-winnable situation. (I never used it back when the game was live, only on homecoming)
Best bet is to join or start a team to take on the contect you want. - Old fashoned, but its going to work better everytime.
