Amen to that. I dunno about everyone else but for me, when it comes down to doing the Acc4 quests its the 3 trash on stage 1 that are the hardest part! :S
Using my light team I can out-heal the damage that the bosses in stage 2 and 3 do to me from normal attacks and non-rage overdrives thanks to the heavy atk-down debuff rotation I have in it while coupled with Gaia's 2 "blocking" abilities. I mean it takes about 30-40 minutes to do the quest depending on what elements I go against but I can do it with no pot used so long as, like LeCrestfallen mentions, none of them decided to spam out combo attacks or tunnel-vision one person.
The pride weapon helps alot against the trash as since it takes a fair few turns to put even one of them down theres a lot of random damage being thrown about, especially when they start overdriving.
I can easily see them being a god send too for fire, maybe wind (depending what characters you use), thunder and dark teams as there is so little cross-healing for them to keep them up at higher hp levels. My fire team especially suffers this as other than the soul I use and Brynhildr they are just pure dps with no healing and no way to debuff the enemy's atk so they take a lot of damage with only a small heal every so often to help recover it outside of enemy dropped pots.
