Consider the following:
- If you ever bought costumes in SF4, you got at least 10 colors to go with it. You bought them in packs of 5 characters for $5
- In SF5, when you buy a costume, you get 2 colors, and you have to unlock the rest. Even Premium ones that require money. That's bullshit. Why should you have to unlock something you paid actual money for?
- In SF5, to unlock said colors, you have to do it FOR EACH COSTUME you buy, not just each character, meaning you have to go through Survival 3 times successfully for each costume you buy. Considering how much bullshit Survival is, it makes people not want to play it AND buy less costumes because the value involved in doing so is poor.
- Seeing the same 2 colors online and in Tournaments for characters gets boring as hell
Also, Survival Mode has a good amount of Fight Money locked behind it.
