Shockwave Pulsar was killing all/most of my team last time I faced him if I didn't have invincibility up (even if I was summoning a GF he would often do enough dmg to kill that GF and the character). I had Revive/Full Life and Recover on my characters to quickly reset my team, but I guess it also made it harder that I don't use items or the Defend command. The only time I normally don't attack/limit break is when I summon Doomtrain early or I am healing, which is only vs a couple bosses occassionally.
