I was trying to max the battle pass (still have 10/12 hours on my time zone) and the weekly missions disappeared halfway through. Is this normal?

i have no idea what happened, but the past few days my crosshair always just locks onto the enemy's torso instead of head and i can't seem to break this habit. i've also started spraying way more instead of bursting/tapping with the vandal....

A friend of mine said that of Valorant will keep adding more and more agents, it will die the same way overwatch did. What are your thoughts ?
