Let gear pieces be equipable in "costume". This game has a lot of really cool items and sets you never really get to see, this option would let me cruise around with my amazing looking lvl 40 elemental weapon without having to commit to it's damage. Maybe I wanna rock the amazing looking Valkyre set, but can't forgo the stats of PoS. I could finally utilize my large assortment of hats as well.
"Beginning of an adventure!" Whenever I see this red quest that I can never complete, it triggers a Vietnam flashback.
Change the name of the "God-Like Control" medal to "God-Like Skill". I believe this change would make the game twice as great.
