People can be butt hurt all they want but at the end of the day both Mina and Iroha are really popular and were at the top of the fan polls. It makes perfect sense to include them. And anyone whining about their designs is over a decade too late, they look almost exactly the same as their original designs. KOFXIV's DLC was based on fan requests/polls as well. The same thing is being done with SamSho.
