Person A spends all his free time swinging that sword, working on power, precision, and technique.
Person B spends all his free time picking herbs, making potions, and mining ore.
WHY does anyone think that Person B should have just as easy of a time killing said troll as Person A. If there was no scaling the point in leveling combat skills over secondary skills would not exist.
I simply don't understand why anybody thinks this comment has merit. The *actual* comparison here is between the following two situations:
Person A who spends half his time leveling his 1-hand and his armor, and the other half searching for exotic elvish women, drinking skooma, and falling into drunken stupors (sleeping).
Person B who spends half his time leveling his 1-hand and his armor, and the other half grinding herbs into potions and hammering dwemer metal into bows and swords.
Person B encounters, arbitrarily, *significantly* more adversity in his world than Person A. He will live in dread of each level up - perhaps going to far as to avoid sneaking or purchasing from shops, so as not to inadvertently contribute to "unproductive" leveling. It doesn't make sense, it isn't realistic, and most damning of all, it isn't fun. This is why ES fans uniformly begged Bethesda to dump the level scaling aspects of Oblivion. They pretended they heard, and claimed they would do something about it - yet as far as I can tell, it's worse than ever.
To those who say the Person B should use their crafting to boost their combat prowess - it simply doesn't compensate for the enemy leveling at medium levels. At level 50 smithing, you can make Orcish weapons and armor (as Rocketeer said), and at level 50 alchemy, you can make a pretty mediocre health potion (assuming you have all the perks available at that level). That isn't going to do anything against veritable gods you encounter in every pathetic crevice, shack, and cave that you find at level 25.
To those who say "crafters shouldn't expect to be good at combat" - you can't craft your way to victory (thanks Nemesis7884). If crafters can't be good at combat, then they can't complete the *vast majority* of quests in the game (excepting of course, that they throw wave after wave of their own companions at the enemy).
To those who say that the OP is "whining", read it again. It's a legitimate complaint. No one is insulting your mom or your dog or your car - it's an aspect of the game that can genuinely be improved. Heck, he isn't even saying he doesn't like the game - he has two different characters in a double-digital level for heaven's sake, less than a week since launch.
A suggestion to all you hack-and-slash gamers who bought Skyrim only to kill dragons with a big mace - you have nothing to add to this discussion, so don't post here. Rather, this discussion is for people who like the more sophisticated aspects of the game - crafting, speech-craft, sneakiness, etc. These are the people that I (and the OP) would like to hear from.
