It really just depends on what people value more, so they have to make their own judgement.

I wanted a second Akashi last event, but she only dropped from E-1. It wouldn't have made sense to me to not play the rest of the maps for days in order to farm her. In the end, I cleared everything on hard and had 2 weeks to grind E-1 (well, still didn't get her, but I don't think easy mode would've made a difference :P).
