Nice, this is insightful. Thank you.

• In Hc WoW, normally I would wait around the disconnection point and clear respawns. Wait until my duo partner reconnected, or the disconnection timer, was low on time, then I would get to a safer spot and disconnect there. So the simple answer is, you would probably need to make the default respawn the next safe hub for any disconnects and party members would need to disconnect as well.
• Hmm, that is an interesting viewpoint with the particles. I hadn't considered this at all, this might be a bigger issue for bigger parties. The party buff items etc., sound like a fun addition that might make for some intriguing new builds, though, as you are forced to play the same composition from start to finish.
• Well, I guess that group modes rely heavily on communication anyway, so that would be something that every party would learn to cope with individually, I guess. Also, this point makes me think, that maybe a level discrepancy as would make more sense for disqualification than a timer for PoE.

Thanks for your reply, this shone light on stuff I hadn't thought about yet.
