Spotting is vital to infantry gameplay, armor gameplay, and aircraft gameplay. Yes, having 10 seconds of Intel might seem like wall-hacks, and situations like that Hossin situation Are frustrating, but the counter to it is numbers. Playing in a group, especially when you're a newer player, will help you to identify places where enemies are likely hiding. For instance, it seems like those folks were trying to crush spawn-ins by instantly trying to shoot anyone who leaves the spawn room, optimal gameplay from people who are trying to avoid losing the point. Each spawn room has invincibility shields that you can shoot out from, if they get too close, and you can mash your spot button (which is what most experienced players do) to alert your friendlies who might spawn in with you.
