Not only it’s roster bound, but also if you crash = you lose everything
you go away for 5 seconds = after 30s you get kicked and lose everything
you don’t to enough damage = you lose everything
you die right before killing boss = you lose everything
Korea game in a nutshell.
Yes you can’t afk anynore on chaos gate 
Just don’t do chaos gates anymore. Leave them to bots.
It’s the only way to send a message to the devs that something isn’t working.
Ofc, you can keep crying and trying to do that content for 4x150 gold of shards, but that’s hypocritical, unintelligent and selfish.
Just my 2 cents. I’ve given up doing both CG and GS because of the same reason - I’m shit out of luck so whenever I try to do that content, 1-3 people show up.
Last time I went there, there were 4-5 bots with me inside but there was some barrier which needed breaking and they just stood there watching me break the barrier.
When I broke it, I hoped they would come inside with me, but no. They just stood there at the spawn. The only thing I was left to do was F2 the fuck away.
Great content. Much fun. Big rewards.
Keep doing it if you want this game dead.
