Let's redefine "damage taxes"

[Leiron]

Absolutely not. Proper balance would be ~5% from top to bottom of the ladder. What we have currently btw is ~11%. Ease of play absolutely matters, otherwise you are punishing harder Jobs

This was stated way back at page 6, but I would look to point out that a percentile discrepancy is not the end all, be all.
The highest I peeked at briefly was about 12687.
A 11% difference is about 1395 damage leaving 11,291 rounding down.
That isn't something to be concerned about, as there is no encounter currently where an 11% difference is going to result in a wipe due to lack of DPS.
If it does occur, it is usually due to errors in rotation, poor balance in boss HP (which SE is infamous for), or other factors.
Its exceedingly rare where such a difference will make any difference in end game content at the minimum ilvl.
So don't get so heated about it. It isn't worth it.
Mind you this is with aDPS, as you utilize rDPS and nDPS the numerical difference decreases.

Seriously, the percentile usage can be pretty deceptive because its the same as someone bringing up likelihood of cancer.

If smoking increases the likelihood of lung cancer by 50%, but the actual rate is .000000001%, it may be statically significant but it is meaningfully significant.

tl;dr It is a game, not your life, chill with the flaming.

DNC and BRD are also harder than MCH. Being lower satisfies proper balance and being close in potential satisfies viability. Imagine crying "utility" over Curing Waltz/Minne/Paean

That is bad balancing.
You don't balance around difficulty ever.
Difficulty is meaningless with competent players.
