Just because it is Diablo doesn't mean it has to be mindless.
I am all for requiring some thought and tactics if you get through to Hell.
Sometimes having to retreat a little, use different abilities, a few tactics etc. instead of mowing down everything, while spamming potions, until you get to a boss sounds appealing to me.
It is Hell after all and by having it play a little differently to NM and, in turn, Normal adds more variety and longevity.
Potion cooldown and the limited healthorbs could help provide this.
Sure, if you played like always, taking a lot of damage in the process, you would be required to make more trips to town to heal, but that would just be one playstyle. Others may play it safer, taking less damage, so they can get by on the healthorbs and a potion here and there, thus requiring fewer trips to town.
Can I have more playstyles please, instead of spammable potions?
And as Polo said, I also think having some areas where TP are unavailable would be interesting. I think it is hard to ever feel in danger or get nervous about tackling a set of mobs when you are always free to click a button and run away instantly.
You have to understand, the characters would have to be greatly improved in order to fight without potions and TP. Especially for boss fights. In Diablo 2, I am certain that I couldn't have beaten the game without the aforementioned two.
Also, TP was, in effect, disabled at the area where the ancients resided. It's been done before, with half-successful results; the player could just TP right before the ancients anyways.
Running away is, and has always been an option in DIII. If not with TP, it is usually possible to just escape into the previous level.
