I would prefer to see a more complex balance system at play. Not that I know anything about the mathematics required to set one up, but ideally it would take into consideration many variables: Stat/Skill/Prof Allocation, Heirlooms, Level, Banner, Loadout cost (scaling for different stat/skill/prof allocations), Generation, KDR and more? Probably not a realistic desire, but I'd love to see it anyhow.
