If you had the power to add one feature no questions asked, what would it be?

[ReynTime]

"Savage" MSQ mode for doing MSQ from the beginning in a party of 4 and not feeling like bringing a nuke to a fist fight if you have the friends to play with.

Scratch that I'd bring back full cross-classing. Balance can sod off.

Oh, and also gonna throw this one in here:
Split the Red Mage's arm into two pieces (main hand and off hand) so that we can glamour them separately.

As I've said before, I'd love it if RDM, MCH, and AST had their weapons split into halves. RDM would have the blade and focus so you could glamour them separately, MCH would have the gun and lunchbox (which, let's be honest, about 90% of the game would immediately glamour away the instant they added an "Emperor's New Aetherotransformer" you could get ahold of).

AST, meanwhile... I know most people think the obvious suggestion would be the card sleeve that hangs at the AST's side, but I actually think it would be way more fun to be able to glamour the cards. Replace them with Triple Triad cards, or rectangles of pure fire or light, etc.

Scratch that I'd bring back full cross-classing. Balance can sod off.

Balance notwithstanding, I'd really love more content like Bozja. And by that, I mean "content where the usual expectations do not apply"; Lost Actions and essences made for some really interesting play.

I doubt we're ever going to get back cross-classing, because this game is already becoming a nightmare to balance (and we've demonstrated, as a playerbase, that we need padded walls or we'll develop a party meta and kick 'underperforming' jobs from PF -- witness the fate of certain DPS jobs early this raid tier).

But Bozja demonstrates they're willing to let us wander off the beaten path, as long as we do it somewhere over there, a safe distance away from raid balance implications.
