Not really, because all CC's has less CD than GNB Limit break.
Sure of course GNB Limit break looks devastating if you have a DRK/WAR/AST party with coordinated attacks.
But overall GNB is bad, can't make big plays alone and depends too much of your party/raid setup and how the enemy plays, want to use Nebula? sorry no Tanks in your range to target.
DRK = Invulnerable / Pull and bind /Range damage / debuff
WAR= Dive/stun/chain/slow/remove guard-debuff / cannot be CC etc.
PLD = Stun / Protect / Invulnerable /Range damage
GNB = One stun every 60 seconds if you manage to survive, no range options, no slow,bind or debuff (only lb)
