Overall dr should be nerfed fo everyone, but remaining dr shouldn't even be across the board for a type of job.

There's no reason a ninja with the mobility, healing and shielding it has should have same dr as a dragoon or reaper with the mobility they have, they should have next to none and melee players in general need to learn better positioning instead.
If you jump in first into a 1v5 as ninja or monk, you should get deleted instantly within a second, you're being an idiot doing that, your job is to wait for tanks or a dragoon or something to engage first, then you go in and start killing backliners, who also need their dr nerfed aswell.

If you don't get that, don't play a job like that.

Before this dr crap, if you played like this, you'd get tons of kills blowing up bards, black mages, healers easily because they all already spent their skills on the frontliners and have nothing left.

But nah, better go in first and facetank 7 people, then complain on the forum to become a tank yourself.
