I would recommend not doing that as I believe that this is a crutch and steers the player into believing that a sub-optimal style of play is actually a preferred one. I'm actually surprised that you recommended suicide running for that specific weapon; there IS a good weapon that players like to get there, but it's the Zweihander (though it might not be the best weapon for newbies as it's extremely slow).
Here's the problem with what you're recommending: you're advocating a turtling style of play that, yes, will help limit deaths, but that's not actually a good thing. Making mistakes (and dying) is part of the learning process. If you just sit behind your shield all day, you might do a little bit better than players who do not but you will learn at a much slower rate. Plus, you should experiment both early on and throughout the game to find out what weapons and what style of play you enjoy, as well as what works for you. Additionally, while you can attack with your shield raised if you're using a spear, it should be noted that you need to lower your shield when you're not in danger of being attacked because having your shield raised results in a greatly reduced rate of stamina regeneration.
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.
