when people stop laughing or contributing
Honestly, if you don't joke around and have some fun during raids, then that's definitely not a raid I would ever want to be in.
when u wipe a lot cause u guys cant communicate properly. then its enough. still u guys must have an awesome guild. i still remember one time before the first ruby sanctium boss i was on my pally tank and equipped my horsemans sword for fun and accidently summoned it. ops
pulled teh boss when half the party was afk. i laughed so hard after everyone came back dead and was like.. wtf??
Pretty much trash and farmed content.
Very little joking during progress and between wipes.
Joking is too much when in fight and people are losing focus and die to stupid things that are easily avoided.
