You hit the nail on head. Everyone becomes a "Spawn beacon" once out-of-combat. Most players don't pay attention at all when they are the last member of the team alive and, instead of staying prone in the corner waiting teammates to respawn, they die silly by rushing and whole team needs to take the walk.
I play Recon as my main and I completely disagree with these fanboy wishes that he needs to have the Beacon back.
If you play the sniper class, i.e. camping afar from the real action, the spawn beacon is meaningless and 99% players will use it selfishly. Also, it takes only few seconds to pause and stay out of combat.
If you play behind the enemy lines or right in the mix of it, you will probably use the Spec Ops route that gives you 1.5 seconds earlier out-of-combat.
I don't mind Assault having the beacon. At least it will be somewhat closer to the objectives.. Also, the whole Assault class is currently a bit lacklustre...
