For trials and raids, I would caution being liberal with LB3s. Yeah, it does a nice chunk of damage, but most of the time we're talking maybe a percentage or so off the boss' total HP. If you're early on in the fight and things go south within seconds, congratulations, you now have no Healer LB3. Know the risk, especially since this is pertaining to roulettes where you don't know how familiar your party is with the fight.
