XP Boosters are broken, or the game is designed to waste too much time.

Hello,

XP boosters of all types are broken.
They keep running out while you wait: To find a game wait for it to load (hope you chose a popular mode).

Wait for the briefing animations, wait for the squad to run up and pose. Choose your class? wait for the match to start, it's had enough people for like, a minute but hasn't started starting yet.
Wait for the intro animation, wait for the countdown, you're finally playing, it's been 4 minutes, your booster was for 15.
Match ends in 6, the other team doesn't know what a domination is.
Wait for the after match report, wait for the progression animation, wait 40 seconds to stay in a squad then another 40 to match make, back to map loading, briefings and pre-match WAITING.

Your booster runs out.

They don't even sell them in the store, so what's the issue? If they're vibe coded and you don't know how to make them apply ONLY to play time, say so? Then maybe just ADJUST XP gain up a bit.
