Tank limit break

[Kirisu]

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.
