Actually the main problem I have with CaS was (at least in SC4), it seemed one costume per character was made specially for them (and looked really good) and one costume was made in CaS (and the quality just wasn't there).
That's not true. If you choose to customize a character, and then choose to customize the colours of that character's 2P, you can see there's a clear difference in quality, especially with all the shadows. Technically, there's 2 versions of every 2P in the game. One version which is a single model and is in higher quality, and the CAS version which is in individual parts. The single model version also detailed variations for armour break.
