All the "exclusive classes" of GMS (Jett) and KMS (Hayato/Kanna) get no love from Nexon lol.
No hypers, often plagued with glitches, no attention during patches.
Heck, Sweeping Sword's camera glitch has never been addressed since its release as well as willow dodge's messed up activation. With the additional bugs to dodge rate and Falcon Dive, Hayato is becoming almost unplayable. As much as I hope they will deal with these problems soon, I seriously doubt they will.
