Tank limit break

[Klb600]

Tank limit breaks are used in a number of situations. They get used at scripted moments where you're designed to use it to survive a big boss attack during a raid encounter. They're also used to extend the fight so that you can see more of it during progression, and can be used to cheese and completely bypass certain mechanics so that your team either doesn't need to learn them or can gain more uptime as a result.

if it is used in scripted moments then its superficial and isn't impactful nor does it turn the tide of battle like the other role limit breaks.

dps never use their Limit Breaks either except the very end of a given fight. That's not very impactful either, nevermind turning the tide of battle. At least Tank LB3 lets your party survive Boss LB's that would otherwise cause wipes, like Alexander, and Omega.
