See in my previous post, if someone from group 4 leave the raid (group 4 is resized with one less player) then the whole groups 6 and 8 will go up of one raid frame, what i want is to have each group to have their position and not move if someone leave. and i'm sure i've seen somewhere that it's doable without anchoring every groups to UIParent.
It's hard to explain.
I've got a screenshot i'll edit in a sec
In the screenshot someone from group 1 left the raid, now see how group 3, 5 and 7 are gone up of one raid frame; well i'd like to prevent that and have 3, 5 and 7 at their original position even if someone from group 1 left.
