Accepted answer: no
I'm pretty new to the game, and plan to do something like this - I basically like the Dragonplate Armor so, I was thinking how early in the game can you get it. Through power-levelling (in this case, getting Smithing to Lv100) it can be done at almost any point of the game. So I can just use that Iron Dagger trick to max out smithing, fight some Dragons quickly to get the required Dragon Bones/Plates, and then make my armor.
But I've seen people say that if one levels up their, say, smithing too much without leveling up combat skills (I'm playing a sword-n-shield warrior, so say One-Handed) the enemies will become much harder to handle.
To remedy that, I saw another trick on YT - right after the dragon attack in Helgen, after you get a sword, you can just keep attacking Ralof/Hadvar, Wait to allow them to regain health, and repeat to get your One-Handed up.
So, by doing all this (power-leveling Smithing and One-Handed) I should be able to get the Dragonplate armor after defeating the dragon in Whiterun's watch tower without screwing up myself. My main question is - am I doing anything wrong? If no, well, thanks. If yes, what? And then what would be a good time to start the power-leveling process?
