D4 tends to give Raiden problems getting his offense started, so it's really about being unpredictable with your offense. Telekicks can be blocked and punished with a stand 1 VB combo or shocker combo starter, rolls can be punished the same way. Don't rely on JIP too much to get a combo started since she will most likely be lowering her hitbox with D4. Work on your spacing and making reads on telekick/roll, also don't be predictable with tele as mileena can roll it on reaction.
This is another one of Raiden's 5-5 matchups.
