Powerlevelling in a single-player game just makes things overwhelmingly boring. Sure, it might give you higher-levelled items and skills earlier on, but all it really does is reduce the enjoyment of discovery and progress as you journey throughout the story.
I learnt this the hard way through the iron daggers trick :/
i agree it is boring, so i utilize all methods to raise my skills, sometimes i'll just pay for skill training, but other times if i want a perk by a certain level, yeah i'll grind a skill for 10 or 15 minutes, but since i don't rely on just grinding because it is boring, i utilize it when i need to....like i want to be able to dual conjure, you need a 100 at conjuring for that, and i don't feel like waiting till level 80 to use it, so i'll utilize some grinding in order to get it to 100 by level 50 or so, but if someone wants to spend 3 hours firing fireballs at giants or mammoths etc, its their playthrough, i'm really not into dictating how others play their game. a 20 year old kid might not mind grinding for 3 hours, an older person like me prob isn't gonna do it quite as much...i want to spend more time actually playing the game...but i will defend someone else's right to grind a skill all they want.
