I think it's more of a defense for people who dc. Had a fright where healer dced after our 11s clear and during the loot distribution it took him ~200 seconds to reconnect (300s countdown timer used as a stopwatch). If it was 30s or even 150s he'd have lost out on his twine for no reason beyond network lag.

I suppose it doesn't need to be 300s. But at that moment I'm glad it was.
