So I come from HoN and I've been wondering for a while now why the GPM values in Dota2 tend to be higher, even though the timings I get my items at remain the same. A friend explicated this is because Dota 2's gpm doesn't consider gold lost by deaths, ie. its "pre-death" gpm. I find this a little strange, as it benefits different heroes to different degrees ie heroes that die more get more of an advantage in the GPM calculation. I'm of the opinion the GPM calculation should include gold lost by dying.
Anyway, is there an easy way to calculate or find out overall GPM that is inclusive of gold lost by deaths?
