Prohibit class/job changes inside dungeons

[Jinko]

I thought about point two as a suggestion earlier on before I posted this. In the end I opted against it. If you increase Ranged accuracy via Bard, people will just stack ranged. If you increase MP regeneration via BLM, people will just stack BLM.

Even if the buff is not stackable ?

It also mandates that you should have a party of "every" class. I don't want to see a static one dimensional party of "PLD/WAR/BLM/BRD/WHM/MNK/DRG/Random Job," although it would still be more desirable than job stacking.

Well lets not forget that in future more classes will become available lending new aura's and play styles and diversity to party mechanics.

Bullet point three is also a suggestion, but I am not sure the removed bonuses would matter that much. I know on Coincounter it might cause an issue... but other fights I can't see this as a viable option.

Well that's a balancing issue then isn't it, its down to SE to make fights more dependant on that bonus, so if it were taken away people would think twice.

Which is kind of my whole point with the aura's per class, as i said though I'm not really a fan of punishing players, I think it would be better to reward them for making a diverse party.
