Why, why would you do that, WHY!!!
Because the game encourages such behavior. All gameplay mechanics encourage certain behaviors. My partner. Brash, used to put her character into sneak mode, point her character into the corner of the prison cell by the hanging chains and hit the "always walk" button. She would sit back, have a smoke, wander out into the kitchen, get some coffee, go to the bathroom, come over to see what I was doing, ect. Thirty minutes later, when she felt her character had leveled Sneak skill high enough she would start the game. Later, in the cave section, just beyond where the rats break through, she would point her character into another corner where the ceiling was especially low and hit the Jump key over and over and over for 10 minutes. She would always pick a low ceiling because her character would hit her head and return to the ground faster. She wasn't the only one who did this. Oblivion's game mechanics encouraged it.
I'm not immune to this kind of thinking myself. In the early days of Oblivion, if I intended to play a character who used a claymore I would give that character an iron dagger to start. Since Oblivion simplified the older game's previous separate blade skills into one Blade Skill it was faster to level Blade by swinging a dagger. Even after I had switched to a claymore I would sometimes use an iron claymore instead of a level-appropriate one, because using a cheap sword in Oblivion leveled my Blade Skill faster. But I didn't stop there. I would intentionally let my iron claymore degrade almost to the breaking point so that it did
still less damage. Oblivion's game mechanics encouraged this sort of counter-intuitive behavior.
