At this very moment, I chose to enter a gate and join a random party, the party leader is very much AFK and its been five minutes. Seems kind of unfair that leave party or joining another party (for 10 more energy) are my only options, it cost me 10 energy to get here.
I think if you want to leave a party and go solo, you should be able to any time. Though I recognize this could affect things from a coding standpoint. If this could be implemented, this would be great.
A form of this already exists at the tier 1 to tier 2 crossover (and I'd assume the same is true for the tier 2 to 3).
Thread was originally "Leave a party and continue on alone"
Update: Slight hope for the idea being approved :D

Update 2:
It actually got in the game. Thanks everyone who helped out in this (or other threads where I pointed it out).

Now you don't have to be forced to go along with something you don't like, or wait for an AFK leader
Maybe if a party leader goes afk, leadership should switch to a non-afk group member. Would that solve the problem?
