Can we please address the elephant in the room and reduce these particular respawn timers + possibly increasing the RNG on the Invatations? Or make em not a drop shared by group loot rules? Like sigils of wisdom?
Also ban some bots camping these spawns, it is insane.
btw where does it drop? some people says its drop-only from 3 new rare monsters in Karasang Wilds, but on wowhead someone said it dropped from rare monsters all around pandaria
The invitations have been confirmed to drop from regular Pandaria rares by multiple independed sources
source on being the case for mop classic?
WoWhead comments, as well as different people I met in the Brawler’s guild are all saying they got it from regular rares, but mostly in the higher-level zones
then drop rate is close to none 
i killed more than 70-80 and not a single inv dropped, amazing 
nvm just dropped, after 70-80+ rares killed
off normal rares too right
Yes but I suspect that the new PvP rares have a bigger droprate. I got mine after 25 kills
