Tbh the dresses and most of the characters look better in 6, like Kasumi had no neck in LR but in 6 she does if you compare win poses, and the lighting makes the characters have more dramatic and varying looks over LR's same panned lighting and colors looked too saturated at timesThe more I look at these revival costumes, the more I feel like the costumes and characters all looked way better in last round than in 6. I haven't purchased any of the returning costumes for 6 but am almost tempted to just go back to last round and just use the costumes there .
I wouldn't mind if they brought back the Senran Kagura pack though; its likely the only crossover pack that could return. I can imagine NiCO dressed as Naraku.
If they do another SK pack I say they reassign the characters to have different costumes. Some of them were hit and miss and just didn't make sense like Mila as Hikage(Nico) or Momiji as Homura when neither have anything in common besides fire. Also didn't understand Helena as Haruka, they would have been better off making her Shiki who is also french, and has her hair dyed an unusual but passable shade of blonde xD
