I have no idea if I'd rage quit, I think part of the reason I'm so into C-rpg in the first place is because you create your own custom character and can equip him how you see fit.
I'd probably play a lot less. I would deeply miss my Samurai character & my array of different tribute ALTs (Mord_Sith, 7 Samurai & random others that I've made in the past just for fun.) & of course the unique look of the battle field where everyones different play styles meet up, Templars, Roman Legions, Spartans, Ninja, Samurai, Vikings, Nomads, Knights(both good & evil), Squires, Pages, Arabs, Turks & of course Cross dressers & the brides.
I'd be very sad to see them all go in favor of one select play style/time period.
