All debuffs (Stun, Flattened, Bound, Poison, etc) will still affect you. The skill only grants Super Armor. It does not make you immune.
There are a couple of frames left between the activation and the effect of the skill where you can still hit Elsword, canceling the skill (though the red super armor outline may persist due to lag or some other reason).
You are still affected by KD calculations, so if you hit the KD limit, you will still fall down.
The movement speed buff is not listed at all, despite being part of the effect. The increase is around 10% and is not affected by normalization.
