What's "bad" about obtaining them? They all seem pretty easy.
I mean, aside the Chocobo Racing one which requires quite a lot of time/dedication (unless you already have a good racing chocobo), everything else is pretty easy/fast to obtain?
I mean... some of the main stories (especially WotG) might require some time to complete, but it's a couple of days' work and shame on you if you didn't do them already!
Seriously, the only hard/timeconsuming Vorseal that I can think of atm is the Chocobo Racing one. That's quite the dickish move. I apreciate SE "inviting" us to experience content we never experienced, but >40 days of work for that is totally not in line with nowadays' standards.
