They rarely ever Defaults now that I'm using it, and I've been seeing really dumb decisions where Spellcasters, healers and summoners would spend their additional brave point to try and deal pitiful melee damage to my kairai'd swordmaster tank.
It's almost sad.

Stillness with Hasten World is OP. I didn't even abuse it, but to know that if you are in a jam you can use stillness, get both BP back the following turn in order to revive and heal and stuff and be good to go when stillness ends is a life saver.
You can also cheese with Stillness but that's no fun. May as well go 4 valkyries and abuse jump.
I was using Hasten World with an Abilinked character early on, and I forget which boss battle it was, but one of them was absolute brutality with that ability on, getting crushed one attempt after another. I turned the difficulty down to normal mode, and it was still virtually impossible to win. I took off that ability, and suddenly breezed through that battle. Right now, I'm only in chapter 3, but I'm using a performer with a maxed abilink to "My Hero" and Mimic x 3, and SLOW WORLD, to some slightly OP effect***. Some bosses seem to be cakewalks with Hasten World, and others seem to go into beast-mode with it.
*** It only costs 2 BP, and it restores up to 12 BP for the rest of the team, so combined, it equates to a perma-slow on all enemies, and a slight speed buff for my team.
