-The crafting is an issue due to the way Bethesda has slowly eliminated fixed loot in favor of leveled loot lists (which I agree is an issue). This is particularly an issue with Daedric artifacts and other faction uniques which had enchantment scaling based on the level you started (or finished) the quest. However, the only way that crafting ever (completely) nullified quest rewards was if you meta gamed using enchanting/alchemy/smithing loops.
If you're going to throw Skyrim under the bus as a failure, then throw Fallout 4 under the bus as well because they've essentially stripped out the unique loot and quest rewards in favor of an RNG system which can reward you practically the same items. Additionally, some weapon categories like the sniper, semi auto, and full auto guns don't have any unique counter parts. This games loot system was built with crafting in mind, which is a massive problem.
-Archery was actually the strongest play-style with melee coming in as a close second. Either play-style paired with sneak was devastating. Also, the only school of magic that was problematic was destruction due to the lack of scaling - enchanting sort of alleviated this but didn't really fix the underlying problem (scaling). Pure conjuration was incredibly strong.
