Ninja is weak, like very weak.

But fflogs already does that for you, no need to calculate it yourself.
You can just look at the rDPS numbers, which already redistribute numbers based on damage buffs (see https://www.fflogs.com/help/rdps).
What you should not do is manually add damage from TA to rDPS, that would be counting TA twice.

So all in all you're making a good point, if TA was twice as strong as it is now ninja would bring the same overall damage to the raid as a black mage.

Oh didnt realise it was already a thing.
So according to it, ninja indeed is underperforming by 10% anyway, so i was wrong, should get another buff.
