usually when i'm tabbing and i hear a roar/howl in the game it makes me want to immediately click back into the game, i'm not entirely sure why i do this though. but no, i personally don't get any urges to roar/howl back.I too click into the game immediately after/during a howl/roar. Listening for howls/roars might be a great way of recruiting whilst tabbing out, despite all the false alarms there'll be.
