As i was lately in a timewalk raid i noticed that TMW loaded the Timewalk-Instance (5 man) conditioned group, which is sub-optimal. So i'd like to suggest to add a seperate condition to load when in a Timewalk Raid. Love your add-on btw :)

and maybe would torghast as a loading condition be a good idea :)

If blizzard is reporting TW raids as 5 mans then that's not something I care to fix or workaround. You can always just combine the Instance Type condition with the Group Type condition.

Torghast can already be determined with the Zone condition:
