Personally I wouldnt get bored exploring killing randoms wherever they might pop up. It keeps the game from getting repetitive and boring fast. Baal runs get boring really fast.
I have a feeling that we will still see multiple boss runs though, even with the supposed idea that they want us to get the best loot from trash. When you look at it from the beta level, which I know, I really shouldnt do, its honestly a zerg to the SK.
Even in Inferno, whats to stop this. What I see, will be, rush to any known location where there is a boss or a permanate event where they are guaranteed loot. Such as, jondar, and SK. Yes they will kill the elite/champion/randoms on the way, but why not rush to the guaranteed loot droppers?
Are they going to lower the percentage of the loot that these boss/events can drop or have? Or are they going to make it to where the more you run certain events/bosses the percentage lowers accordingly?
I myself, have ran the SK run multiple times on multiple characters and I just dont know. Ive had new characters get absolutely nothing, literally nothing, from him before. And characters ive ran multiple times get a rare drop.
