Probably it will do some good, though SE has been a bit inconsistent with nerfs, recently they've seemed to hold their grounds more (ozma, nidhoog and shinryu comes to mind) but since they've already nerfed something in the past in response to players backlash (though I'll concede that it was to mitigate players leaving if an harder dungeon appared, hence why we have expert roulette in the first place) is a looming shadow imho.
