In Valorant, the perception of the "worst" spot can vary depending on the player's experience, playstyle, and team composition. However, some areas can be challenging to control or defend, making them difficult for players to hold. Here are a few of the spots that are commonly considered challenging in Valorant:

Bind Hookah - As you mentioned, this spot can be difficult to hold as it requires coordination and ability usage to gain control. Additionally, the narrow entrance makes it easy for attackers to catch defenders off guard.

Ascent A Tower - This area is challenging to defend due to the multiple angles attackers can use to gain control. Additionally, the small room at the top of the tower provides little cover, making it easy for attackers to pick off defenders.

Haven C Long - This area is challenging to defend due to its long range and lack of cover. Additionally, attackers can use abilities like smokes and flashes to disrupt defenders and gain control.

Split B Heaven - This area is challenging to hold as it provides a high-ground advantage for attackers, making it easy for them to pick off defenders below. Additionally, the narrow entrance makes it difficult for defenders to retake the site.

Overall, the worst spot in Valorant can vary depending on the situation and the team's strategy. It's essential to communicate with your team and use abilities to gain control of challenging areas to succeed in the game.
