The people saying they miss FFXI mobs, well, in FFXI grinding out in exp parties was the only way to lvl up, so of course those were harder. Open world mobs in FFXIV are intended for you to go out and kill solo, which is why the ones in dungeons are much stronger.

I don't know if I would want to do an exp party like this, maybe once or twice for nostalgia's sake, but I'd probably get bored doing the one thing over and over (plus, it'd need a lvl sync more like XI's) but, I'm all for it if people wanted to do it. It would give another way for people to lvl up. Although I'd more prefer leves and dungeons (particularly dungeons) have their xp rewards boosted to make them more worthwhile than fates.
