I get a whisper while gathering quests. "Are you doing Chillmaw?"
Eager to get 2 more seals than usual, I say, "I can be. Invite."
I wait a minute, then say, "Invite?"
Wait more . . .
Deadly Boss Mods informs me he's busy fighting in Azjol-Nerub.
He whispered me about Chillmaw either while in an instance, OR he took an instance queue right after inviting me to do a quest. And then he refused to acknowledge my whispers.
What the hell?!
I eventually decided to put him on Ignore, as I was too annoyed to not chastise him if he finally deigned to whisper me back.
I can go back to being perfectly content with my Chillmawless grind. I don't need 2 seals that badly.
