The LFG menu offers an extraordinary means of going to various zones, some of which may otherwise require 2-3 intermediate steps from your current location.
The purpose of this "micro-guide" is to help players understand how they can use LFG to their advantage. I have to say that I am in no small part motivated because of a Faathim task force I joined where I watched other members come from whatever zone they were in, go to Peregrine, go to Firebase Zulu, then go to the Chantry, all while I was begging them to drop from the team, use LFG to port to Faathim then they'd get there immediately.
Since a picture is worth 1023 words, give or take:
Let's say, for example, that I'm in Sharkhead and someone is fighting Jack in Irons and Eochai and I'd like to help. I can simply select "A Tangled Plot" then choose the "Lock the event for your group" button, then "Queue". In a short second, I'll get the familiar prompt to join the league. Click it and next thing you know, you'll be in Croatoa in front of Katie, just a quick super jump away from from the GM fight.
Here's another example: You want to join a Hamidon raid. I see all too often someone go to Founder's Falls, travel to the Eden gate, go into Eden and then take that looong haul to the Hive gate. All you have to do is select the "Trials" tab then choose "[Prisoners of Eden] Woodsman". You'll magically appear in front of the Woodsman who is a short hop from the Hive gate.
Some relevant details to keep in mind:
Like any use of the LFG, all team members must be in the same zone. So, for the Hami raid example, you should drop from any team before using LFG to transport, then rejoin once you get to Eden (or the Hive).
Do not use this while you are on a tf/sf/trial. Doing so causes you to drop from it. You are ported to the contact you selected but dropped from the tf.
It will work to transport your whole team to a sf/tf/trial contact (if everyone is currently in the same zone). So if you're doing missions in Peregrine and one sends you to say, Brickstown, you can choose Manticore.
LFG doesn't tell you what zone these sfs/tfs/trials are in, so this is mostly for people familiar with them already.
You will NOT be able to use this to transport to contacts you haven't unlocked yet. In the image above, you can see that Katie Hannon is unlocked for me (the text is white) but just below, you can see that the Ernesto Hess text is grey, meaning I haven't unlocked him and therefore can not use LFG to port to him. (I could for Moonfire though).
You will only have sfs/tfs/trials shown that you are eligible to participate in. If I had shown you this menu from a level 30 character, then Ice Mistral and Numina would not have been on the menu (both have a minimum level of 35).
It should also be noted that the current WSTs will be highlighted. From the image above, you can see that Mortimer Kal and Admiral Sutter are highlighted in purple, denoting that they are the current WSTs.
I hope some of you find this helpful and it gives you some food for thought about alternative means of moving between zones. If I can clarify anything, or if I have something outright wrong, please let me know.
