They just need to add ALL of the characters to the ladder/tag ladder because 10 fights, even on expert is way too short. They should also have the cpu in ladder wear the alternate costumes.
Just because Spamming is a strategy YOU don't agree with doesn't mean it's stupid.
Anyways, I only play ladder/tag ladder on expert.

Attention
Go into fatality tutorial
Select Smoke and then choose MK3 Sub Zero
Perform Smoke's first fatality and as S.Z. is dying his costume will turn grey. I though it was a pretty cool glitch.
