For the Nyame armor are most people going for rank B? I feel like its best for most melee jobs? Like if you play cor/ thf/ brd/ drg? I sure do like path A but... the WSD... and with a mythic and earrings/ ring/ cape / neck having store tp already on them...
B is good for more than just melee, it's the best WS pieces for 90% of the WSs that mages use too.
Here's the ""problem"" with augmenting with the other paths of Nyame:
A: The problem here is that Nyame is a T4 set. The T3 sets, which you have to unlock before you can get Nyame, do basically this for the jobs that really would want access to Malignance but don't have it. So the T3 sets + Malignance existing depreciates the use/value a path A would get you. So why drop all that money and "effort" augmenting something that you can already have (and possibly be better/more unique than just PDL+DT+Store TP).
C: This sounds really tempting. MAB+50 MBB and MBBII? For DRK/PLD/NIN especially that all sounds really good... except... The MBBII you're getting is all of 2% per piece. And while 50 MAB > 30 MAB... for these MAB starved jobs, you're not going to see that huge of a difference. (Especially with how often PLD/DRKs be bursting.)
D: I don't know what they were thinking with this. I haven't tested the D body R20 aug, but if it works like how I think it says, then it's just marginally worse than the BiS piece for SMN... so PUP/BST might get better use from that? but I feel like they too have better options. Everything else is just sorta.... there. BST probably has the best excuse to do this... but... T3 set.
Because the biggest thing that makes things like path C and A less useful for you to pick than B is that the things you'd want to use them for are already there on the base gear.
Need pure DT set? You already have it without the augment.
Need MBB and MAB for jobs that don't really get it? Guess what. It's already there.
Nothing is stopping you from using a path B augmented piece in your MBB/MAB or DT sets. (And as mentioned above, the T3 sets + Malignance exist and can usually offer you better or the same level of DT with better/more relevant offensive effects.)
tldr; path B gives you your bang for your buck, while ACD all have equal or better relevant options; plus you can still fill in what you need because the big relevant stuff isn't in the augments.
