The longer a challenge is, the more that things need to be solved with heals. It isn't necessarily Merlin but it is basically Merlin, Tamamo, Medea Lily, or Hans as the prime candidates with Jeanne pretty reasonable too. You could use Martha but there's more ways to go wrong. Mandating consistent healing is tantamount to mandating arts NP cycle and that is the main limiting factor to the challenge type. The battle is too long to cheese with snowy castle or something and buster based teams can't last long enough. Quick teams don't have the longevity either. This results in the healer arts cycle gravitation. If they want to have different kinds of challenges, they need to choose mechanics that don't simply result in long battles but rather require specific and careful strategy.
