Selfish DPS Balance

[Shamox]

Kinda like how AST is for healers. there is a threshold of cards ast must spread before it's more viable than whm do to the large dps disparity between them.

This threshold is RNG doe which is pretty bad, the whole card system based on RNG is just bad.

Theoretically:

who do you want to hit a NIN's Trick attack Vulnerability; a SAM or BLM who could passively deal 20-30% or even 50% more damage on to the target with vulnerability on top of the vulnerability's normal debuff, or any other DPS

If there's a BRD or a MCH in your group, which is the case in any meta composition, DRG is actually better than NIN, so the answer is pretty obvious.

who should an AST give a Balance buff to; a SAM or BLM who has a trait that stacks a moderate-to large (30-50%) Potency boost when given any non-user Potency buff from another party member, or any other DPS

Making plans around an RNG buffs that most of the time is gonna be an AOE card anyway, yes.

both of these "parties" are parties of two, no other jobs there, its the NIN/AST with one other DPS

???

the idea for selfish shouldn't be "it doesn't help," it should be "all take, no give"
of course, this is all theory talk

You need to understand that as long as there is gonna be utility buffs, any selfish DPS is gonna suffer from not having some.
Your solution would either :
-Not make SAM strong enough while not giving it any advantage in a non meta comp (oh ye you gotta realize that a good grp with a meta comp and a bad grp with a meta comp are 2 distinct things, also, selfish DPSs really rise in low to medium skill groups)
-Or, it'd be so strong that it'd just take another job's place which would simply create another issue.
