tl;dr
No more averaged mf, your mf is your own.
Legendaries are going to upgrade. Mobs don't heal after long periods of time nor do they enrage. repair cost reduced by 25%
Tons of changes to classes, skills/runes that are weak & never used will be improved upon and builds will be diversified.
No more invulnerable minions. Two handers will be stronger.
iLvl 61/62 weapons can have a damage roll just as high as any i63 item. Nerfing fire chains, shielding, reducing damage of some of those imba as fuck skeleton mobs that just do ridiculously stupid damage (skull cleavers).
Increasing regular inferno mob health 5-10%, increased their blue/yellow drop rate by factor of four. Decreasing elite/champ mob health by 10-25%
lol dude, I couldn't even remember that I posted that tl;dr since I was drunk as fuck. Thanks for it, though.
