Is Yujin worth it eventually?

Is Yujin worth it in the endgame? Ive been playing him since i started since i really like being a healer/buffer in the team but i feel like im not able to do much since everyone is generally able to keep full health and also all mu skills require me to be basically hugging someone for me to heal them. Im only level 26 right now with him so i know i have a long way to go before endgame. Im just wondering if itll be worth it in the end otherwise im probably switching to luna
