Raid 20, Raid 30, Raid 40
Hey don't know if its possible for now or not. But may you can rework the Raid Frames a bit for the modern WoW?
For now you can only Setup for Raid 6-30 (1 Anchor Point and Settings) and Raid 31-40 (1 Anchor Point and Settings).
I like to Request a third Option!
Raid 6-20, 21-30 and 31-40 so you got 3 Raid Frames for Mythic, Heroic and Open World/PvP 40 Man.
So you got more flexibility for Mythic Raiding without touching the Heroic Raid Frame.
If it's possible now and i missed it then sorry for that.
