Nothing happened, it was always like that.

Problem is the limit gauge is a shared ressource and people are worried to use them because they maybe get yelled at for using it at the wrong time (or at least what the other person thinks was the wrong time). So they hold onto the LB until the last moment, when it is definitely not the wrong time to use it - but because they use it too late or not at all (because they forget that the LB exists) they actually doing it wrong anyway.
