Imo, the Unreal fights are just a way to show players who joined after ARR was over what the fights were like, somewhat, when they were current. Lord knows old fogies like me never shut up about the old days.

The reward system could stand to be better to encourage further participation, but the fights themselves aren't exactly something that will stand up to a competent group. Keep in mind, since they're exactly the same as fights from years ago, there are myriad guides for them already, AND you can go unsync the old extreme and watch all of the mechanics play out, if you don't know the fight at all/don't remember it.

I kind of look at it as a way to try and bring old vet raiders and newer raiders closer together. I know it's a very small gesture, but I appreciate it, because MMOs are a shared experience. The shared experience gets better if more people can share in it on some level.

As far as why does it suck that some new skills get shafted/disadvantaged with new kits vs. old fight. Simple. The fights were designed for older, far different kits. Part of this game, and all Final Fantasy games featuring the job system, that goes against our nature/modern mores is the fact that a big advantage on the job system is that anyone can bring any job. It might not be the job that you like, but you can bring jobs that aren't disadvantaged, if it matters so much to you. The nature of this game has always been that some jobs fair better than others, slightly, depending on the fight scenario. Some fight scenarios change which tank is better for what dynamic. Same for DPS. Same for healers, sometimes (this time).
