While some of your whines are perfectly valid opinions (opinions, mind you, not facts), this one is pure nonsense.
In what possible universe does D3 force you to "fight the same path all over again looking for elites" to do a magic find run?
You feel that you must run a certain specific zone because the mobs are a tiny bit more densely packed than the second-densest zone? Do you realize what a tiny, tiny difference that is compared to magic-find runs in D2, where nobody ever ran anything except a short, short list of bosses?
Why do ppl keep justifying Diablo 3 flaws by comparing it to Diablo 2?... it's a logical fallacy, and nothing else.
Because people also say that certain things in are D3 are flaws by reference to D2. I have done it plenty of times. The games are sufficiently similar to do so.
The above qoute however is a complaint which applies equally well to both D2 and D3. You have to repeat the same process many of times, buy hey that's Diablo.
