Don't want to burst your buble but D2 was tons more easier then D3: mobs AI was horrible and if you were a pet class they wouldn't even look at you, dmg was so much over the board that on both my reanimation necromancer and lightning sorc i could easilly clear anything on max players (think it was 8x instead of 4x now) solo without any problems. D2 had tons of silly mechanics that took challenge factor away even before you aquired BiS gear, D3 is much better and way more challenging game, althought it's challenging to such a point that it's hard to believe for me that anybody will reach Inferno on hardcore character.
