If you look at the real problem of botting, and many players who essentially make D3 full-time jobs without botting, and then compare them to others who make minimal time investments...it gets confusing. Only one thing is factored into the current equation...GR level. But, what if Blizzard factored another important element into the equation -- time invested on that toon? It might be interesting and would result in vastly different leaderboards. Botting might go away completely on its own because if players are ranked by an equation such as hours played/GR level, then botting would shoot someone in the foot.
This would be terrible. It would make playing in meta 4-people groups mandatory. Anyone playing solo will have much less paragon and gem levels per time played than those who group up and so for the same gear level and GR completed they'll have much more time played. They would never be able to compete.
