Perhaps Lisa didn't convey it properly, but I think she's calling BS on the story as told. I find it hard to believe that if Vent really did pipe up multiple times in raid chat that vent was malfunctioning, and that multiple wipes had occured (presumably as a result) that EVERYONE would have ignored multiple cries for help.

The boss fight in question, Twin Dragons, also has a lengthy runback. It's not like there wasn't time to autofollow and alt+tab to try and fix vent, peek at a strat, or both. Also, why are you accepting readychecks? Maybe for a couple attempts you think you can "wing it," but clearly that wasn't working. You could even not run into the boss room as a way to get attention. /say for speech baloon chat. /yell even.

As other commentors have pointed out, he's probably a combination of entitled guy and unprepared guy. While unpreparedness is occasionally tolerable in an impromptu run, entitled guy is still revilied. Either way the story stinks of lies.

Lastly, what does the letter writer hope to accomplish? Assuming for a moment that they are not crying wolf, they should know to basically tell their side of the story to the Guild Leader, and perhaps look for a new home. So at best, if "vent" isn't lying, this letter is simply a "woe is me" cry for attention.
