Im sure everyone here has had those few bosses that you killed with seconds remaining, or had that unlocked LBC that got off a lucky HomingMissile and causes some havoc and had to fight it down with every ounce of power you had.
This game is all about minimal upgrades and changes. 99% of the gear in this game wont matter if your goal is just "are we fundamentally capable of killing this mob". A purple belt mnk in scorpian harness and wagh h2h can kill a boss, but a full usu destroyers weilding BB mnk can do it faster and get past those "oshit" times when you dont have that extra minute to spare.
As for voice of reason: Im always reasonable

, Im just not always nice about it.
