Not really a poor idea, but I really don't see why staff shouldn't just do it how they've always done it and spare themselves the extra work of meeting the requirements of players who can't handle the extremely challenging act of pressing a button at the correct time - the event seemed very successful in the past

I'll add that it comes as no surprise that the players who want this to be a boring, single-player time investment are the same people who want to reset their own spar scores, put limitations on active towerers, and other anti-competitive/pro-boring acts
I personally don't understand how someone can play an online game if they aren't motivated by competing or playing against other people
