I can solo Chaos dungeons fairly easily, something I get to regularly practice because 2 or 3 people usually bail out of the chaos dungeon half way through. These people also tend to afk or contribute little, dragging out the group experience.
I am at a point I will probably not bother to group up for these unless something is done about it. I prefer to play with other people in MMOs where possible, but the current environment is quite toxic and never experienced this when I played LA on Russian servers.
The reason people bail out half way through is because you have front-loaded the loot into the first half of the dungeon. Ideally, it should be evenly distributed, but I wouldn’t be opposed to 50% of the total rewards being locked behind achieving a 100% competition of the instance to dissuade this behaviour. I know the streamer community who informed the public about the unbalanced loot distribution said do not leave in the middle in groups, but that message hasn’t sunk in.
