sounds interesting. bit worried that it will make inferno either a) too easy once you're level 100P, or b) impossible when you first hit 60 (or when the patch first hits).
maybe add a difficulty above inferno to go with it? i dunno.
read alot into all the changes, and it makes me want to play it again. Funny that I was moaning to somebody just yesterday about the fact that I needs something hard to attain like D2 did to keep people playing (paragon levels sound good).
Supporting the game for 10+ years is one thing, keeping people interested is another, but this all sounds good.
