Is the alchemy/smithing loop thing patched? It totally breaks the game IMO. And yes, I know you don't HAVE to do it. But I'm always a perfectionist when playing, so I kinda do. Powergaming comes first for me, roleplaying after that. If I start to play Skyrim again I want to complete everything possible. But I hate you can make +324235345% weapons and stuff.
Also, I hate the legendary skills thing which basically makes the idea of different builds useless. Character building for me has always been one of the main things in RPGs. Then again Skyrim is such a massive game it doesn't hurt to make a character that has the ability to be perfect in everything.
