Some simple measures to avoid DoL problems.

1) Change the party make up.
Ideally, for me, this would mean a ten person party. The same as it is now, but also with 2x DoL required. However, there are ways you could work it with a 8 man party. Perhaps one less DPS, one DoL.

2) Lock jobs.
This will stop people from joining with one job then switching to DoL (or vice versa) immediately and trolling the group for their own personal gain.

3) Make DoL beneficial and needed.
There are so, so many ways this could be done. For example, imagine if tracks could only be spawned through gathering. It's the job of 8x people to defend the DoL from mobs while they do their thing. Have DoL gear drop as well as DoW/M so the DoL aren't left out. Encourage teamwork. And so it's not just a "let's just keep the mob busy until the DoL is done, then all die and reattempt" - give the DoL enough to do at each node(s) that they will be kept very busy throughout the fight, or even allow them to benefit the fight a la 1.x Hamlet.

4) Allow Join in Progress / Kick from content, and remove the 120 minute lockout.
Quite frankly this system has been a disaster from the get-go. With locked jobs and no timeout the problems would be no different to raids/dungeons. So kicking and joining in progress should be perfectly fine, and those who abuse it can be reported appropriately.

5) Personal opinion, not so important to the DoL problem: Make Need/Greed the default loot system, just like in dungeons.
It's basically what people are doing already anyway, and anyone who doesn't do it is considered a troll by the majority. We can get around that problem with a normal need/greed system and locked jobs.

These changes would...

- Encourage teamwork.
- Encourage use of DoL.
- Encourage fighting to defend DoL.
- Encourage exploration and movement around the field (ie, less zerg in one spot a la Dino Island).
- Not discourage parties from working together to protect the DoL.
- Hopefully encourage a lot more positive vibes!
- Remove most forms of griefing/trolling commonly found in Diadem.
