Is sorc broken on this server?

I made my sorc like 4 days ago on this server and for some reason i feel like in my awakening cartian's nightmare and Grim reaper judgement are bugged. Cartian's nightmare literally feels like it does 0damage except for the burn on it, and GRJ feels like it misses half the time. I really don't think it's an accuracy issues because my friend (mystic sadly) has like 30 less gs than me and i feel like that my GRJ misses on him half the times. Also i with 170 AP i and like around 200-250 acc (idk what it is), i do literally nothing to manes with cartian's nightmare. I just want to know if sorc is actually playable on the server or if I should reroll because it's literally unplayable like how tamer is on this server.
