Hell Difficulty

[Rataxes]

I don't do cows, I don't get rushed, I don't rush, I despise people who do. Just thought I'd get that out of the way.

The point isn't inciting people to "complete" quests.
It's inciting people to "play" through the quests.

Is indeed, forcing people to spend hours in the same area searching temples that all look the same and reaching a dead-end in all but the last doesn't exactly create an incentive though. The reward remains the same but the time consumption and tedium of being stuck in the same area, fighting the same monsters and not making any progress, multiplies. No, that doesn't create an incentive. Such a change would likely cause a drop in people bothering with the quest at all.

What kind of "reward" is that?
Per your own words, the "reward" is that you can skip a lot of areas of the game.

Yep, and move on to other areas, see change, fight different monsters, use different tactics, see your character progress. The game grows stale quickly if you do the same thing over and over again or are stuck too long in any one place, which is why I don't ever cow run and why I constantly create new characters with new ideas and plans in my mind. I'm not skipping any area by knowing before-hand which temple is the correct one, what am I missing by not exploring the other temples? They all contain the same monsters, it's all in the same area (the one I most likely already fully explored while searching for the correct temple), I use the same skills, the same tactics, my character would cease to evolve for a time since I would soon grow beyond the allowed 5 lvl difference that allows for decent XP rewards.

If not having to play the game is a "reward" for you... then why are you playing it in the first place?

Correction, more variation is my reward.

If you find the game "tedious"... then it's time to move on.

I enjoy variation, levels 1-40 are usually the most exiciting times for my characters, because that is when I see most change, most variation, most evolution and progress. Being stuck in a single area searching identical temples, fighting the same monsters and using the same skills and tactics for an extended period of time certainly isn't my idea of fun, no more fun than doing cows.

Yeah, like killing cows, more cows and more cows is less "boring" than playing through the variety of the five acts.

And yet, here you are, advocating that quest-solving should involve more repetition.
