"Meant to be enjoyed in solo environments":
Without other people you get 1/4 of your job's best value, if that.
Besides the strictly party based reward mount, you also have most spells that add mechanical value and interest behind party content,
without party content you miss out on a lot of power and mechanics. Very lamed blue mage if you skip that party step. And so far has been most popularly used in parties to expedite grinds like this FATE one or moogle tomestones. So yeah. Lol.
Even though I'll probably still want to salt the earth about blue mage my more logical and 'for the best of whatever 'this is supposed to be'' side wants to suggest that such a change is a switch for FATE events. Because taking it away entirely will remove one of it's few 'nice to have' values. I don't think it would be ideal, given situations where things are quiet at least, to have everything be immune to one of the key reasons blue mage exists in the state it does currently (doom, tail screw, lv5 death, missile, etc).
Just my tortured imo though lol.
