1- The lack of many good clothing choice kind of bothers me. Even if you can layer them, most of the outfit seems to be floating over the body, and many items that were in SC4 kind of degrades in quality because it looks so "large" for no reason now. I haven't played BD, but my friend told me that you could adjust things like hats in there to fit the character's head/hair. So even if we have all those options for accessories and how meticulous you can be in the placement, there's always things that they take out for no reason it seems. There's also the lack of main character clothing (people who reached lvl 50 still doesn't seem to have unlocked any of them).
I've only had the game for two days, so of course I haven't unlocked and seen everything. However, I won't hold my breath for much more, especially after seeing SCIV items in the first DLC CaS pack (which hints that a few or many SCIV parts will probably be released as DLC instead).
2- Voice pitching/toning. For some voices, you can easily adjust the pitch higher without it starting to sound robotic. However, some of them can't even be adjusted a bit (-6/+6) without it starting to already sound weird. They had no problem with the pitch option for both high and low in SCIV, so what happened here? I really don't understand how this was just ignored while they could have just taken what they did in the previous installment.
