Over time since the May 16 patch, do you see a shift in Weight Classes used?
Lights were less seen from the Resizing, only some recent event in the past few months that had a bit of Light focus brought them back to some degree.
I figured Assaults would shrink with this patch. Not sure if Lights would make more of a comeback so that leaves Mediums and Heavies at the predicted highest use.
I theorize one way to fix things would be, over time, modifying Tree values by Chassis and maybe Variant. Right now the only difference is a few Node types between IS and Clan.
