Unless I'm fighting a giant Dream Toad, all guildleves I've done in the past are pretty boring and (dare I say) a little hard to sit through.

It's not "casuals'" fault that the gameplay is so rigid and uninteresting, or that the difficulty on everything is set so low (and no, I am not referring to timesinks as a difficulty). It's SE's fault for not 'seriously' tuning across multiple skill or participation levels.
