I have used this profile with a lot of classes and it has enough button to insert all of your spells :). It helps a lot in optimizing rotation due to the central position of most skills while keeping a minimalistic ui design.
If you are coming from default blizzard ui (retail) upper bar might be incorrect and you may need to rebind all spells.
At 1080p I use a 0.64 interface scaling(If the bars are not like in foto try changing interface scaling in elvui->general).
