Makes sense. Dark Souls has a lot of options and can be overwhelming, so sticking to just one can make approaching the game easier. If all you have is a hammer, approach everything like a nail.I don't necessarily disagree with what you've argued. All valid points.
I have several friends who have the game, started it, and within an hour or so dropped it because it was too overwhelming and unforgiving. "Masochistic" is how they viewed playing the game.
Yes, turtling with a spear is not a great way to push through the game. However, for a new player it can give them enough ability to observe some game mechanics and feel a little less frustrated at the beginning.
As I said, I'm still on my first playthrough. I didn't start with the spear and I understand the frustration The game can cause a new player. After a few hours in the game I picked up the spear and it allowed me some breathing room (figuratively and literally] to observe some of the game mechanics I struggled with or missed to that point.
I was able to make progress while learning and, from the perspective of a player new to the gameplay, made for a much more enjoyable initial experience. I also learned the spear approach was a short term use for me and moved on from it.
In short, if it helps someone to not give up on this great game it has proved it's worth.
My hammer was playing a SL1 character with only a reinforced club and a handful of pyromancies (that I never even use); with only minimal HP, armor, and stamina, I learned to approach every problem with careful movement and deliberate skull-bashing. Useful skills to have on future characters-- even with armor and health and weapons, it helps being practiced at not getting hit.
