Wanted to make you aware that the "message suppression" feature (the one that prevents players from spamming map chat too often) also affects LFG group descriptions.
To explain: When I change my group description too frequently, I am eventually locked out of changing it. I'm a new raider and encountered this bug/feature when doing W4 Deimos this week. Since that fight requires 3 unique roles (tank, oil kiter, hand kiter) in addition to your usual druid + chrono composition, I had to frequently change the description as players came and went, and quickly found myself no longer able to do so.
Thank you for your time and attention.
