Well...many aspects of quests such as puzzles and platforming are in R10 quests and that's a completely different type of gameplay than fighting R10 mobs, but it's still part of doing the quest. The runs to quests are more about story/immersion/setting etc. than fighting the mobs in the wilderness as you go, even if grabbing rares and such on the way is also part of it. I get where you are coming from though.
How much value is story, immersion, setting beyond the first run through?
I believe most of us agree this part of MD is a win. But after the first run through that value is depreciated substantially and diminished further on successive runs. I would be OK with not having teleporters for the first week, then adding them later. But considering the LFM system and having a low game population, many runs start before a full party forms. This mechanic discourages IP LFMs and certainly discourages new players to the pack, or even worse, those to the game.
I respect your point of view, but the reality is that is your opinion. Others may have a different perspective. Deciding to have a port only unlock able to 3 places is not respecting both viewpoints, it is only respecting one and becomes a very one-sided argument. Having options, like RL respects either viewpoint, because now you can choose to participate in the journey to the quest or not. Or if you are new, unfamiliar, or joining an IP, you are not off-putting other party members time waiting for you to get there (or getting lost).
