Something like that. But thinking more about it, it's not much practical.
It should be nerfed, that's my point.
Imagine when you're losing a firefight, them you need to fallback, just like irl, to regroup again with your entire squad. On that way, the squad leader needs to play more cautiously to avoid being fully overwhelmed by the enemy.
A change mechanic on rally will, for sure, change the leader playstyle. And I think it's the way that a truly squad leader should follow.
I don't know about you guys, but every squad leader should be more supportive and less aggressive on overall. Many leaders dont give a **** about die and keeping relying on rally when they should stay alive for entire round or at least trying to survive for the most part of the game.
Sorry for my poor English, but I think you guys will get to the point.
