I couldn't help but stop after reading/posting over and over about the imbalanced nature of things, and even now knowing that a patch is right around the corner I have to just mention rq.

if job_a has:
weapon basedmg > all
hp > all
def = tank
str = DD
vit > all (encouraged by it being a dmg modifier)
abils that out dmg DDs and generate enmity in amounts > standard tank abilities
self heals and dmg reduction on par w/ all melees

isn't that unbalanced?
Does no one at all see that?
Should that playing field not be leveled?

Point out one job that can boast all those things ... THEN ... point to another that can match the first.
If/When you can't simple logic says there's a lack of balance.
If I throw a dart at a wall that has all jobs listed randomly, then throw another those 2 jobs, regardless of what they are should have pluses and minuses that make them level/equal. That's not to say all jobs should be able to spit out the exact same dmg, or have the same HP, but rather to say that,

job_a has dmg+++ hp+++ def+++ enmity+++
is not balanced where

job_b has dmg+++ hp-- def--- enmity++
job_c has dmg--- hp++ def+++ enmity +
are balancedish.

To make all jobs balanced by bringing everything up to the level of the OP job would just mean everything is +++ on every job. That'd be f'in stupid.

Yes my example is super crude, but it does illustrate the point, and if the only argument to my logic is that there's more than 4 stats to consider please don't bother.
