Same or larger planes now weigh less then their predecessors. See A350-1000 vs 777-300er. The Airbus has a 94,000 lb lighter MTOW for the same dimension aircraft. So consideration of capabilities beyond just size need to be factored in.

I don't have an issue with pay banding, if the bands actually made sense. In my ideal world, if banding were used:

Super Jumbos (A380/747-8i class)
Large Widebodies (777/787/A350)
Small Widebodies (767 all variants)
Large narrowbody (757-200 and -300/A321)
Medium narrowbody (all 737, all 320, C series etc)
Small narrowbody (anything smaller then above)
