Ranged DPS role is about to be excluded from all content

[Karja]

Let me start my post by saying that it's pretty obvious that all ranged dps except for BLM currently need help.
I think everyone knows that at the heighest level BLM currently from all ranged jobs does by far the most damage.
My question(s) would be at which level should these jobs be balanced?

What I specifically mean with that is I checked E4S for the last week on FFlogs and looked at difference in DPS for the 10, 50, 95 and 100 percentile.
And DNC at 50% deals 9.36% less than a BLM at 50% but at 100% DNC deals a staggering 14.34% less.

I also looked at the DPS difference between 10% and 100% e.g.
BLM 11782 compared to 15815 (4033 difference or 34.23%)
DNC 11108 compared to 13547 (2439 difference or 21.96%)

or 50% and 95%
BLM 13194 compare to 14767 (1573 difference or 11.92%)
DNC 11959 compare to 12901 (942 difference or 7.88%)

It's a similiar case for the other jobs in the ranged role where no other jobs even reaches 25% difference in the 10-100 category or 10% difference in the 50-95 category.

It seems to be the case that while BLM on all levels deals more damage than the other ranged (even at 10%) it also scales better with player skill and/or gear.

If I manually adjust DNC dps at the 50 percentile to 13,194 which would be BLMs DPS at 50 percentile and add the same % increase DNC currently see going from 50-95% on FFlogs for this fight it would be at 14234 DPS for the 95% bracket and be 533 DPS (or 3.61%) behind BLM.
BTW I know that it would probably not play out like this entirely if SE buffs DNC or any other ranged dps.

If I do the same thing going for both jobs going from 50 percentile to 100 percentile
BLM 13194 -> 15815 (19.87% increase)
DNC 11959 -> 13547 (13.28% increase)
New DNC 13194 *1.1328 = 14946

DNC at 100% with parity on 50% on BLM would still be 869 dps (5.5%) behind BLM.

I don't try to justify BLMs DPS here I'm just genuinely interested what peoples thoughts are about this, how much influence on DPS should player skill and general job difficulty have.
