There aren't really any events that require fully released copies of any spirits. The only spirits who really "need" to be fully released are spirits like Chihiro, who has good skills, but terrible stats, though they become passable once fully released. Having fully released spirits make life much easier. You get faster access to your Special Skills, you get better stats, meaning, especially if the spirits involved have team-boosting Hidden Power (which both versions of Mumar do).

bittersingle!Pazza is actually vital for a thunder-based Triple Bladder deck unless you can rock a very specific set of fully released spirits (like in my video) and like a margin of error of 0 (Answer Skills activated at all times, no off-coloured questions in the Asmodeus battle), as a TCC 6 75% fire shield means you're basically immortal against Asmodeus unless you answer any questions wrong (and when you do, as long as your HP is high enough, you might be able to get away with it by using Kuon's shield). The 400 extra ATK works out to 230 extra damage against fire, 460 damage against thunder and 690 extra damage against water (base of 460). At 50+ questions in a perfect answering no off-colour questions, that's 11500+ damage (against fire), 23000+ damage (against thunder) or 34500+ damage (against water) per Triple Bladder run. It could save you anywhere from 1-6 turns, which could prove vital, but more importantly limits the opportunities for you to mess up and thus fail the quest.

Offense is the best defense, even when not going with no-heal all-out offense-based decks. The higher the ATK your spirits have, the faster you clear quests, the larger the margin of error is. The higher your spirits' HP, the lower the chances of them ever dying, even if you mess up every now and then.
