Does the new crosshair feel weird to you ?

Since the new update i can't really play comfortable , i feel like the new crosshair is a bit off , i feel like im not hitting what i should , like i have ping? I used to play on short crosshair , i did a costum one that looks exactly like the old one but i think is not ? Anyone else is having this , also why did they remove the defaut crosshairs , i used to like it very much.
