SargentToughie has phrased it better than I could. Don't get me wrong, I like the idea, and I see the merit in it, but she's right. Another problem is, there's a massive difficulty spike between say Garuda Ex and Ramuh Ex. Even with amazing rewards in place, due to the timescales involved, you're probably quicker just taking the penalty and fishing for an easier ex primal than bashing your head against Ramuh Ex. You can't even increase the penalty because then people would just demand to be kicked (people do it even now with a 30 minute penalty, this happened to me recently in Trials Roulette. One wipe because we had I believe 5 newbies in the party, and this guy started mouthing off bigtime at us, saying we can't clear, to kick him, etc, which we refused. He then faked offline to try and force a kick, basically holding us hostage). It's a no win situation there, so I don't think this idea would work.
