AutoDungeonRetry
Tired of having to constantly retry the dungeon teleport during peak hours? Sick of seeing "Additional Instances cannot be launched, please try again later."? Then this addon is for you. Whenever you fail to start a new instance through the new LFD tool, this addon will retry the teleport five seconds after you get bounced out.
This addon should work on all Locales, but the message that the addon prints has not yet been translated. Feel free to submit a translation to me in comments or as a PM.
Slash Commands
/adr #
will set the delay between retries to whatever # is.
Anything else following the command will toggle the enabled state.
/autoretry
may also be used.
