I think its time BRD get some loving

Last time you brought up numbers I tried to show that as long as the bard is doing a percentage of the dragoons damage overall balance does not change even though the gap in raw damage dealt grows.

Lets say your dragoon does 100 dps, and your bard does 85 dps against a boss that has 100,000 HP. The fight will last 540.54 seconds during which the dragoon will have done 54,054 damage and the bard would have done 45,945. The bard did 45.9% of the boss's total HP, and was at 85% of the dragoon's damage.

Lets say we increase the duration of the fight 5x to a boss with 500,000 HP. In this case the fight will last 2702 seconds during which the dragoon will have done 270,200 damage, and the bard would have done 229,670. The bard again did 45.9% of the total damage, and was 85% of the dragoon's damage.

Now lets scale up the dps 5x to 500 dps for the dragoon and 425 for the bard, and a 500,000 HP boss. This again comes out to 540.54 seconds for the fight, with the dragoon at 270,270 damage and the bard at 229,729. This is still 45.9% of the total damage and 85% of the dragoon's damage.

The above shows that duration and scaling are independent of the actual overall balance.

To maintain bards at whatever percentage lower than other dps, it is expected that the difference in weapon damage and stats between classes would grow because if stats grow by 5x, then the gap between the stats and weapon damage should also end up growing 5x which would lead to absolutely no change in balance relative to other classes. As you saw above, when the difference was 15 or the difference was 45, it didn't matter, the bard still did the same percentage of the boss's HP.

Ok, this is relatively easy to show if you are only talking about 2 DPS that comprises the whole party.

[B]But there's also another MNK/NIN + BLM (and when they fix it, SMN) + 2 Tanks that's weapon damage is scaling properly to factor in.

The percentage does not matter. Like I've said so many times, with larger numbers, the raw number of that percentage greatly inflates.
This is going to the extreme, but say a bard ends up doing 1,000,0000 less damage points than a MNK/NIN/DRG 3~4 years down the line.

Do you really expect Paeon to justify bringing a bard and Paeon to make up for that kind of damage?

At patch 2.3 bard was doing enough actual damage points less than melee and casters. Even SMN was very powerful in 2.3.
SE should base it off doing less actual damage points than percent. We are still going to do less damage than any other DPS class. Basing it off percents is going to greatly limit a bard in the future.

This is what I mean that bards are contributing less actual damage to the fight with every other patch.
Every other Job has their weapon scaling properly. Tanks, SCH, WHM, Casters and Melee are get these huge boosts in raw damage with each patch. I could care less how much "percent" a bard does less.

It is still ok now (barely). But SE needs to draw a line of 5 WD points lower than Melee. Not lower percentage.
We're still always going to be lower damage.
