Remove fire damage from A Baddies Grace just to ease the salt levels. MoN changed from stamina regen penalty to -1 stamina to have a more meaningful downside to such a strong mark. Thats the only things I can realistically think of, for the most part I don't think CSM really has much OP stuff. MoN is strong and could use a harsher penalty and I don't think 5 fire damage on A Baddies Grace matters but some people seem to think it completely breaks the game. Some people talk about the NCS being locked to MoN, but if you combine that with a MoN nerf you are just dumpstering the thing. If anything I think CSM mostly needs buffs specifically for Aspiring Sorcerer and Mark of Tzeentch both of which are decently underperforming outside of really niche situations.
