Camille e works by hooking onto terrain. On the current map, she has a small deadzone in the middle of toplane where her e does not work. Trading in this zone is far worse, because then you only have acces to 2 abilities. On the new map they increased this zone by a large margin by moving the walls further apart. This will make her laning fase far weaker. Nobody wants an overbuffed Camille so u/zxc1996819 in the Camille subreddit suggested to add a small rock at the end of toplane river to e on to.
This would also help champs like Gnar and Ornn in their laning fase.
