why is deadlock hated sm?

I am a pretty new valorant player and i really like the strategy part of the game so when I was choosing my agent I really liked the sentinal role. I ended up choosing deadlock finding out later she is v hated on. I dont get it tho her wall is better than sage wall with the new update bc it can cover a bigger area and you can still get picks on the enemy team. you can also see if they are rotaing. The wall has more health and lasts longer than sage. DL can also be aggressive with her net and ult. Also her sound censor can sometimes watch flank or be used aggressively. Idk if its different in high rank but in my sliver lobbies i think deadlock is one of the best sentials (also very easy agent to play unlike cypher)
