my first account is a wizard, it has 320% GF
second account is a DH with 300% GF
next 3 accounts are wizards
My main wizard gets more GPH, but this is probably because he has more DPS (he has 40k dps, DH only has like 23-24kDPS). Also i tweak ALL my profiles for reliability over GPH. Whats the point of having a really high GPH if the bot stops 1 hour after you go to bed? I went wizard for the extra 3 because i found it easier to find GF gear + dps cheaper/faster. This may be more due to my lack of DH knowledge (i basically tried to just get dex and vit for my DH). I also found wizards easier to maintain overall with multiple accounts.
On another note - recently i've been testing MF gear on 2 of my accounts and in the last 24hrs its been paying off better than GF. Just use ghosties loot rules and you start to stash ilvl63 stuff that can easily sell over 1mill per piece. Got lucky on a unique ring worth 8-10mill, quick sold it for 7mill.
Also when i was running D3A (now discontinued) i had 700k GPH on the wizard reliably. This is because D3A would insta quit games even when not in town, so it was literally 3-4 seconds for a closed cellar run, then about 20 seconds for a successful one.
