I agree so much with this, and you can see in comments (here and everywhere else) about how many people never bothered to learn how to use it in any game. In FFXIII, there's a long segment without a character that can use Commando (Sazh and Fang), which is the job that the game tells you it can stabilize the stagger meter so it doesn't deplete as fast (and you can stagger enemies easily). In that particular segment, you're meant to use Ravager and Saboteur (but most people from what I saw ran with dual RAV), because Saboteur's abilities ALSO do this. Whenever I see a mention of "It took me minutes to defeat X boss/this was a slog", I can't help but feel it's just people that either didn't bother to learn how the staggering system works, or didn't understand the synergies required.
